With the publication of this issue of the Böhler Manual, „WELDING GUIDE“, previousissues lose their validity.

Particulars provided about the nature and application of our products is provided for theuser's information. Details of the mechanical properties always refer, in accordance withthe applicable standards, to the pure weld metal. In a welded joint, the properties of theweld metal depend critically, amongst other things, on the base material, the weldingposition, and on the welding parameters.

Any guarantee of suitability for any particular intended application requires an explicit,written agreement for each individual case.

BöhlerProductsWelding Guide

Foreword

Böhler Welding – Your Partner for WeldingWe create solutions for the daily challenges faced by our customers in welding technology – that is the guiding principle of Böhler Welding.

We know only too well, on the basis of the 85 years of our company's history and of theexperience gathered from more than 150 countries around the world, that in practice it is thequality of application that is crucial. Proven and adaptable expertise is essential wheneverextreme temperatures, maximum demands for strength, ultimate corrosion resistance or thefastest possible working are the deciding factor.

From the materials, through the application to the optimum welding consumables, we invol-ve ourselves with all the questions that are relevant for the desired welding result. To thatend, we work in close co-operation with our customers and partners to develop the solutionthat will be most profitable for them.

Nothing is too much trouble for us in the pursuit of an optimum welding result for our custo-mers, and we also offer training and welding demonstrations on-site – from the Arctic to themost remote African wilderness.

For us, as one of the industry's leading innovators, only the best is good enough when itcomes to welding. That is why we work on product development, collaborating with famousuniversities and research institutes where the special equipment and most highly educatedpersonnel are available for carrying out the simulations and measurements that we require.

At Böhler Welding the rule is: it's the results that matter.

Storage guidelines and redrying

1.3. Storage guidelines and redryingStoring stick electrodesCovered electrodes should always be stored in their original packaging until they are used.Electrode packages should, as far as possible, be removed on first-in fist out basis.Stick electrodes must be stored in dry rooms in order to protect them from moisture damage.The storage are should therefore be protected against the weather and ventilated. Ceilings,floors and walls must be dry, and there must be no open water surfaces in the room. The roommust be fitted with pallets or with shelving, since storage directly on the floor or against thewalls is not recommended.Electrode packages that have been opened must be stored in dry rooms, which may have tobe heated to avoid falling below the dew point.

Redrying and processing electrodesIt is recommended that any electrodes that have become damp or that have not been properlystored are redried according to the temperatures given in the following table immediately befo-re welding. Following this it is in any case recommended to weld from a quiver heated to 100-150°C in order to be able to maintain the lowest possible hydrogen content.

Stick electrodes for ... Covering type Redrying Redrying Redrying time recommended temperature in °C in hours

Unalloyed and A, AR, C, RC, No -- --low-alloy steels R, RR, RB

B Yes 300 – 350 2 – 10High-strength fine-grained B Yes 300 – 350 2 – 10structural steels

Creep-resistant steels R No -- --RB, B Yes 300 – 350 2 – 10

Stainless and R If necessary 120 – 200 2 – 10heat-resistant steels RB, B No -- --Soft martensitic steels B Yes 300 – 350 2 – 10Duplex steels RB Yes 250 – 300 2 – 10Nickel alloys R, B If necessary 120 – 300 2 – 10

The redrying temperature is also quoted on the labels of the Böhler packages.

The following procedure is helpful for redrying electrodes:• The electrodes should be placed in a pre-heated furnace (approx. 80 - 100°C);

layers should not be more than three.• Once heated up, the recommended temperature should be maintained for about

2 hours. If the redrying temperature is above 250°C, the temperature should be raised to the recommended value slowly (approx. 150°C/hour).

• A total redrying time (i.e. the total of the times of individual redrying procedures) of more than 10 hours should not be exceeded. This maximum time must also be observed if the redrying is carried out in a number of cycles.

• The temperature should be lowered to between 100 and 150°C before removing from the furnace.

Electrodes that have been in direct contact with water, grease or oil should not be used. Insuch cases, even redrying does not provide an adequate solution.Covered electrodes that are delivered in undamaged boxes or in vacuum packaging do notrequire redrying if they are put immediately into a heated quiver and used from there.Electrodes from damaged boxes or vacuum packaging must be treated according to the spe-cifications.


1-13

Storage guidelines and redrying

Stick electrodes for which redrying is not recommended in the table above may, in some indi-vidual cases, still benefit from redrying. This can be the case if storage was inappropriate, oras a result of other conditions that lead to an excessive water content. The high water contentcan often be recognised from increased spraying or pore formation during welding. In thesecases, the stick electrodes can – unless otherwise specified by the manufacturer – be redriedfor about one hour at 100 - 120°C. This recommendation does not apply to cellulose-coveredelectrodes, which must never be redried.The temperature for intermediate storage in a furnace after redrying should be between 120and 200°C (maximum total storage time 30 days), or, if stored in quivers, between 100 and200°C (maximum storage time 10 days).

Storage of flux cored wiresThe risk of moisture absorption is not as great with flux cored wires as it is for stick electro-des. The core is shielded from the ambient atmosphere to a large extent by the metal surro-und. Nevertheless, the "low-hydrogen" character of a flux cored wire can be impaired by longcontact with moist air. This can, for instance, happen through unprotected storage overnightin a high-humidity environment.Flux cored wire should be kept in storage facilities where the temperature and humidity con-ditions are controlled. We recommend the use of dry rooms, possibly heated, to avoid fallingbelow the dew point. The aim should be a maximum 60% relative air humidity and a minimumtemperature of 15°C.If stored below 10°C there is a risk that water will condense on the surface of the wire whenthe package is opened in heated rooms. This can lead to pore and gas impressions on thewelded seam when welding starts.Welding should only be done with acclimatised wires.When welding has finished, the spool with the remaining wire should be removed from themachine and placed back in the original packaging; the compound aluminium foil should beclosed again as far as possible. It is also possible to use a box such as is used for deliveriesof Böhler welding flux for high-alloy steels.

Redrying flux cored wiresRedrying is not required as a rule. If, in some exceptional case, redrying is needed, this canbe done at 150°C for 24h.

Storage and redrying of welding fluxIt is recommended that welding flux is stored in the driest possible conditions and at the mosteven possible temperature, in order to keep water absorption during storage as low as possi-ble. Under these conditions, fluxes can generally be kept for up to three years. Flux from con-tainers that have been damaged during transport must either be used immediately or put intonew packaging. In order to ensure crack-free welding, fluoride-basic fluxes should be redriedprior to use. Fluxes that are taken directly from airtight, sealed, undamaged metal sheet con-tainers do not have to be redried.

Type of flux manufacture Flux type Redrying Redrying Redrying time recommended temperature in °C in hours

Agglomerated FB Yes ca. 350 2 - 10AR Yes ca. 300 2 - 10

Melted MS Yes ca. 150 2 - 500

The drying temperatures and times given in the above table should be considered as a gene-ral guideline. After redrying, welding flux that is not being used immediately is to be stored at150°C until used for welding. The intermediate storage period should not exceed 30 days.The furnace used for the redrying must not permit any local overheating of the flux, and mustbe adequately ventilated. If drying is stationary, the flux layer should not be thicker than 50 mm.

Certificates of conformity and other certificates

1.4. Certificates of conformityand other certificates

General notesIf wanted, factory certificates or acceptance test certificates according to EN 10204 can beprepared for each delivery. Test Reports according to AWS A5.01 can also be supplied.Whatever the type of certification, it must always be requested at the time of order.

It is essential that the extent of testing is stated for EN 10204-3.1 acceptance test certificatesand for Test Reports. The subsequent preparation of a 3.1 Certificate or a Test Report with atesting scope that differs from schedules F and H is always associated with increased admi-nistration and increased costs. If a production series has already been entirely processed, itis not possible to prepare retrospective certificates.

Factory certificates according to EN 10204-2.2With this certificate the manufacturer confirms that the delivered products correlate with therequirements of the order, including results of different not specified tests.

Acceptance test certificates according to EN 10204-3.1 and 3.23.1 or 3.2 acceptance tests certificates are also prepared if required. For this purpose, testsmust be carried out on the delivery or on the manufacturing unit associated with the delivery.Since this involves certification of a delivery-specific test according to the requirements of thecustomer, it is essential that the extent of testing is made known at the time of the order, or atthe initial enquiry stage. The resulting costs will be charged according to expenditure.

Test Reports according to AWS A5.01If certification of conformity of the product with the AWS (American Welding Society) is requi-red for a customer project, a Test Report should be requested. The Test Report contains, asstandard, a confirmation of conformity for correspondence with the applicable AWS standard,or with the reference to this AWS standard contained in ASME II, Part C. If no further elementsare specified by the customer, the Test Report corresponds to "Schedule F" of the AWS A5.01.The content of this Test Report is comparable to that of a "2.2" factory certificate.

The necessary testing scope must be made known at the time of order for all other schedu-les. In this case, charging will be according to expenditure.

2.1. General notes on the data sectionThe product information on the following pages is maintained consistently for all the weldingconsumables from Böhler Welding. For the sake of easier orientation, the header of each datapage carries information on the subchapter, the product form and/or a colour coding. Thenumbering in the footer refers only to this chapter.

Each of the following chapters is subdivided according to product forms, when available, inthe following sequence: Stick electrodes, TIG rods, solid wire electrodes, flux coredwires, wire/flux combinations and gas welding rods. The last chapter contains a descrip-tion of the welding fluxes.

Each product is identified by its trade name and by a product group.The product description contains some changes from the last issue of the manual.Amongst other things, the classification according to standards has been thoroughly adaptedto the current issues (at the time of going to press) of the EN ISO, EN and AWS standards.

The conversion has also been applied to the information about the base materials.The “Description” section of each data page gives a brief characterisation of the weldingconsumable. It describes the type of covering or alloy, the range of application, the weldingbehaviour, areas of use and general information about temperature control and/or subsequentheat treatment.

The “Typical Composition” gives the chemical composition of the pure weld metal for stickelectrodes and flux cored wires, and for other product forms it gives the composition of thewire, stick or flux. For wire/flux combinations, the reference analysis of the wire and that of theweld metal is given.

The information provided for the “Mechanical Properties” always refers to the pure weldmetal. In contrast, the guide values are based on the evaluations of our permanent statisticalquality control, and are only for information. In both cases, the latest state of the art at the timeof going to press is taken into account.

The “Operating Data” represent an extension over previous issues of the manual. The sym-bols for the welding position and the electrical polarity accord with the labelling on the productpackaging. In addition, you will find information on the stamping or embossing of products,and instructions for redrying.

Information on “Similar Alloy Filler Metals” has also been added. This should make it easierfor you to select a welding consumable if you want to change the welding procedure whileusing the same base material.

2.2. Unalloyed Welding Consumables

ObjectiveThis section provides detailed product information for filler metals that maybe used to weld mild steels. Due to their tensile strength and yield strength mild steels (particularlygeneral-purpose constructional steels) are used primarily in the as-deliveredcondition (rolled, forged or normalised) for welded, riveted and screwedstructures in structural engineering, civil and underground engineering,bridge building, hydro power engineering, tank construction and mechanicalengineering.In each case the choice of filler metal must be appropriate for the materialinvolved and must allow for welding engineering aspects where the ruleapplicable is that the minimum mechanical and technological values of theparent metal must also be achieved in the weld metal. In addition tochoosing according to welding engineering conditions such as the weldposition, edge preparation, work in the workshop or on site, it is alsonecessary to allow for the metallurgical features of the material, materialthickness, shrinkage conditions and susceptibility to cracks.

2-22

DescriptionSpecial electrode for gouging and grooving steels from unalloyed to high-alloyed, grey cast-iron, light alloys and non-ferrous metals apart from pure copper. Easy ignition properties, highgas pressure and therefore high cutting speed. Usable in all welding positions.

Suitable for chamfering flanks, cutting grooves and furrows, as well as for grooving out faultywelds and opening cracks prior to welding.

For grooving, place the electrode as flat as possible against the base material (about 15°), andslightly tilt the workpiece so that the melted material can flow away more easily. Keep the elec-trode in constant contact with the base material. Slightly jerky movements in the working direc-tion make it easier for the material to flow away and improve the economy.

The groove must be ground down to plain metal before welding over.

DescriptionCopper coated wire electrode applicable universally in the construction of boilers, containersand building structures. It exhibits a largely spatter-free material transfer both under mixedgases and under CO2. Through its ability to withstand high currents it has ideal properties forthick sheet welding. Use low-diameter wire for vertical down welds.

The version of the solid wire electrode without copper coating is also available as a TOP versi-on, and it has been designed for minimum tendency to splatter and the ideal feeding characte-ristics even at high wire feed rates. These versions are particularly used for automated welding.

2.3. Welding Consumables for Pipeline Welding

ObjectiveThis section provides detailed product information for filler metals that maybe used to weld pipelines.

The significance of oil and gas as a source of energy leads to the construc-tion and planning of cross-country pipelines throughout the world. In thiscase new high-strength pipe steels place the highest possible demands onwelding technology. As a result various filler metals have been developedthat can cover all the requirements of individual steel qualities.

Cellulose electrodesGenerally speaking the welds are performed in the vertical-down positionusing cellulose electrodes. The use of vertical-down electrodes makes itpossible to use larger electrode diameters, higher welding currents and hig-her travel speeds. As a result it is possible to achieve a much higher degreeof economic efficiency than with vertical-up welding.

Basic vertical-down electrodesBasic vertical-down electrodes excel due to their outstanding mechanicaland technological properties and their low hydrogen content. They are thussuitable for welding thick-walled pipes, high-strength pipe steels or wherethere are high requirements for toughness. They allow the same travelspeeds for filler and cover passes as cellulose electrodes.

Basic vertical up electrodesEspecially designed for welding of circumferential beads in the vertical upposition. The electrodes are preferably used in cases where the imprecisejoint preparation do not allow the use of the vertical down process, or verticaldown skilled welders are not available. Root runs are basically welded on theminus polarity, where as for filler and cap layers the plus polarity should beapplied.

Solid wiresFor the sake of higher productivity and in order to reduce production costssemi/fully automated welding processes are introduced. For these applica-tions the wire types SG 3-P, SG 8-P and NiMo 1-IG have been developed.Both wires fullfil the high quality demands applied in pipeline constructions.

Flux cored wiresThe application of flux cored wire for filler- and cap-layers in pipeline construc-tion is gaining in popularity due to the significant savings potential os this wel-ding process.

Generally speaking these flux cored wires can be grouped as follows:

Gas-shielded rutile fluc cored wire for semi- or fully-automated pipe welding:A key benefit of this type is that they can be welded with constant para-meter settings in all positions. Due to the fast-freezing slag system theusage of high currents is possible and allows for significantly higher depo-sition rates compared to other processes.

Self-shielded flux cored wires for vertical-down welding:As the name states already these types do not require additional shieldinggas as the elements to create the protected atmosphere when welding arealready contained in the flux. The diameter of these wires is 2.0 mm andare easily handled by the welder.

2.4. Weatherproof, High-strength and Cryogenic Welding Consumables

ObjectiveThis section provides detailed product information for filler metals that maybe used to weld weather-resistant, high-tensile and cryogenic steels. Weather-resistant steels are used in all areas of structural steel engineeringand light-gauge steel construction, amongst other things for overhead wireand overhead trolley wire masts, in the form of rod and sectional steel, light-gauge sheets and heavy plates. Due to their excellent strength propertiesthey may also be used for higher operating temperatures (over 400°C) alt-hough in this case the proof stress decreases considerably. High-tensile steels may be used down to very low temperatures in structuralsteel engineering and plant construction, the construction of vehicles,wagons and agricultural machinery for welded structures subject to highstatic and dynamic loads. The cryogenic qualities and special qualities ofsteel may be used down to -60°C without fear of brittle fracture. Generallyspeaking it should be noted that increased care must be taken during fabri-cation and a structural design suitable for welding and withstanding stress isan essential prerequisite since the minimum values of the yield stress rise asthe wall thickness increases. Cryogenic steels are intended for components subject to static and dynamicloads at operating temperatures below -40°C in gas liquefaction plants in theprocessing of mineral oil, for fractionated distillation of hydrocarbons, for thetransport of liquefied natural gas and in air liquefaction plants. Consult thebuilding regulations for pressurised vessels with regard to special applicati-ons.

Weatherproof, High-strength and Cryogenic Welding Consumables – GMAW flux cored wire


DescriptionThe alform® 700-MC metal cored wire is developed for gas shielded arc welding of thermo-mechanically treated steels and fine-grained structural steels. A combination of sophisticatedmetallurgy and precision manufacturing technology offer high strength and good toughnessvalues. The good ignition properties and exceptional feedability result from a higher torsionalstiffness of the welded profile. Thanks to the manufacturing technology, this metal cored wireoffers low hydrogen content of < 3 ml / 100g. The flux cored wire is intended for welding undermixed gas (Ar+CO2) in the PA and PB positions. Very positive results are also achieved withother shielding gases such as CO2, 8-10% CO2 + Ar and in other welding positions (PG). Thiswire is used for high-strength steel constructions in automotive engineering, crane constructionand shipbuilding, as well as for offshore applications and pressurised pipelines.

2.5 Creep-resistant and Highly Creep-resistant Welding Consumables

ObjectiveThis section contains detailed product information for filler metals that maybe used to weld high temperature and creep-resistant steels. The high temperature properties of general-purpose constructional steelsare no longer adequate at operating temperatures above 350°C. Creep andflow processes occur in the steel at high temperatures under load as a resultof which the load permissible becomes time-related. Therefore steels alloy-ed with Mo, Cr-Mo and Cr-Mo-V are used. Small additions of Mo, Cr and V are sufficient up to 550°C operating tempe-rature. Above 550°C increased scale resistance is also necessary. Up toapprox. 600°C it is possible to use quenched and tempered 9% and 12%chromium steels with additions of Mo, V, Nb and W respectively. Above thistemperature special austenitic Cr-Ni steels are used. The basic type contains16% chromium and 13% nickel with additions of Nb. At temperatures above700°C only nickel-base alloys with additions of Mo, W and Nb exhibit ade-quate creep properties. Basically the choice of the filler metals and the welding technology is alwaysin line with the parent metal used and must be matched to its behaviour.

When the welding has been done, the jointshould be cooled to a temperature of less than 80°C before heat treatment in order to completethe martensitic transformation. Cooling down to room temperature is possible for pipe welds up toa wall thickness of 45 mm. If the wall thicknesses are high, or the parts complicated, the stresscondition should be considered. The following parameters are recommended for subsequent heattreatment. Temper after welding at 760°C/min. 2 hours, heating/cooling rate below 550°C max.150°C/h, above 550°C max. 80°C/h. If the annealing times are less than 2 hours, achievement ofthe specified requirements must be demonstrated in the course of a welding process test. In orderto optimise the toughness, a welding technique that ensures small layer thicknesses is recom-mended.

BÖHLER P 92 Ti-FDFlux cored wire




DescriptionStrip alloyed, flux cored wire with a rutile slag characteristic for welding highly creep resistantaustenitic CrNi steels, primarily in flat and horizontal welding positions.

The easy handling and high deposition rate result in high productivity with excellent weldingbehaviour, self-releasing slag, low spatter formation and seam oxidisation, finely rippled weldseams with good wetting behaviour and even, reliable fusion penetration. Plate and pipes witha wall thickness of about 3 mm up can be welded with this type of flux cored wire. The weldmetal is suitable for operating temperatures up to about 700°C, is resistant to scaling, while itscontrolled ferrite content gives it good resistance to hot cracking as well as a low tendency toembrittlement.

BÖHLER E 308 H-FDFlux cored wire,



2-175


DescriptionStrip alloyed, flux cored wire with fast-hardening slag for position welding of highly creep resistantaustenitic CrNi steels. The support provided by the fast-hardening slag allows out-of-position wel-ding with high current magnitudes and high welding speeds.

The fine droplet, low-spatter, very intense spray arc, the reliable fusion penetration, the self-relea-sing slag and the good wetting behaviour result in a high weld quality at the same time as shortwelding times. Additional advantages to its application are the ease of handling, the low heat inputresulting from the high welding speed, and the small amounts of cleaning and pickling required.The weld metal is suitable for operating temperatures up to about 700°C, is resistant to scaling,while its controlled ferrite content gives it good resistance to hot cracking as well as a low ten-dency to embrittlement. BÖHLER E 308 H-FD is preferred for flat and horizontal welding positions (PA, PB).

3.0Preheating and interpass temperature: 150-300°C. When the welding has been done, the jointshould be cooled to a temperature of less than 80°C before heat treatment in order to comple-te the martensitic transformation. Cooling down to room temperature is possible for pipe weldsup to a wall thickness of 45 mm. If the wall thicknesses are high, or the parts complicated, thestress condition should be considered.Recommended heat treatment: 760°C/min. 2 h, heating/cooling rate when below 550°C maxi-mum 150°C/h, above 550°C maximum 80°C/h. If the annealing times are less than 2 hours,achievement of the specified requirements must be demonstrated in the course of a weldingprocess test. In order to optimise the toughness, a welding technique that ensures small layerthicknesses is recommended.

2.6. Stainless, Corrosion-resistant and Highly Corrosion-resistant Welding Consumables

ObjectiveThis section provides detailed product information for filler metals to join cor-rosion resistant and highly corrosion resistant steels.

The corrosion resistance of these steels, which is based on the passivatingeffect of chromium due to the formation of dense, adhesive, thin passivefilms, is brought about by Cr contents above 10.5%. Mo increases thepassivating effect still further. It is possible to differentiate between ferritic,martensitic, austenitic and ferritic-austenitic steels according to the micro-structure in the as-used condition.

Due to their special characteristics austenitic CrNi(Mo) steels are used in themost varied branches like the chemical and petrochemical plant engineering,the pulp and paper or textile industry, for offshore engineering, shipbuildingseawater desalination, the food processing industry, etc. They are primarilyused for the fabrication of storage tanks, reactors and pressure vessels aswell as piping systems.

The choice of filler metal and welding technology should be matched to themetallurgical behaviour of the parent metal and the componentʼs corrosionrequirements.

DescriptionBÖHLER FOX CN 16/6 M-HD is a basic coated stick electrode with a high deposition efficien-cy for welding soft martensitic forged and cast steels. Due to its high chromium content, the pro-duct has a good corrosion resistance when exposed to water and steam. The weld metal is alsocharacterised by an extremely low hydrogen content (HD ≤ 5 ml/100 g).

The electrode behaves very well in terms of its arc stability, weld pool control, slag detachabi-lity and seam cleanliness. It can be used for all positions other than vertical down (use a smal-ler electrode diameter when in position) and has a deposition efficiency of about 135%.

BÖHLER FOX CN 16/6 M-HD is suitable for joint welding and production welding of same-type,corrosion-resistant, soft martensitic rolled, forged and cast steels. Its primary application fieldsare in the construction of water turbines, pumps and compressors.

DescriptionBasic coated, core wire alloyed Cr-Ni-Mo stick electrode. It features a low C content, a limitedMo content (for higher Huey-test-resistance), carefully selected N alloying, and a high Ni con-tent to achieve a reliable fully austenitic microstructure (ferrite content < 0.5%). The corrosionrates in the Huey test are around 0.08 g/m³.h (4 mils/year). The electrode is suitable for urea plants, for exposure to particularly high stresses at high pres-sures and temperatures, for welding components with a high resistance to boiling concentratednitric acid (optimum application for HNO3 contents of 60-80%), where high resistance is requi-red in the Huey test, and for equipment that comes into contact with solutions containing highproportions of chloride at high temperature. As a result of the high chromium content and of theadded molybdenum, there is a good resistance to pitting when exposed to solutions containingchlorine ions. Can also be used for highly corrosion-stressed components in the dyeing industry(bleaching and dyeing baths), in the textile, paper and leather industries, as well as in the che-mical, pharmaceutical and rayon industries.

DescriptionTIG welding rod of type 904L with an above-average Mo content, and very high pitting resi-stance equivalent (PREN = 45) of the weld metal for the pitting potential (according to %Cr +3.3 x %Mo + 30 x %N). Particularly used in the production of sulphuric and phosphoric acids inthe cellulose industry, in flue gas desulphurisation plants and also in the fertiliser industry,petrochemical industry, fatty acid processing, the manufacture of acetic and formic acid, sea-water desalination, in pickling plants and for heat exchangers that are operated with sea orbrackish water.The weld metal is fully austenitic, and has distinct resistance to pitting and crevice corrosion inmedia containing chlorides, high resistance to sulphuric, phosphoric, acetic and formic acid, aswell as to sea water and brackish water. The high Ni-content leads to very good resistance tostress corrosion cracking when compared with the conventional 18/8 CrNi weld metal types. Asa result of the high over-alloying with Mo as compared to 1.4539 or UNS N08904 it is possibleto compensate for the demonstrably high segregation rate of CrNi weld metals with a high Mocontent.

DescriptionTIG welding rod ideally suited to welding ferritic-austenitic duplex steels. As a result of thecarefully adjusted alloy, the weld metal not only features high strength and toughness, but isalso exceptionally resistant to stress corrosion cracking and to pitting (ASTM G48 / Method A).The welding consumable can be used in a temperature range from -60°C up to +250°C.To achieve the special properties of the weld metal, it is necessary to ensure controlled diluti-on and thorough back purging. In particularly demanding cases, small proportions of N2 maybe added to the shielding gas and/or the purging gas.The TIG rod features very good welding and flow behaviour.

DescriptionSolid wire electrode for steels such as 1.4539 (904L) with an above-average Mo content, and very highpitting resistance equivalent (PREN ≥ 45) of the weld metal for the pitting potential (according to %Cr +3.3 x %Mo + 30 x %N). Particularly used in the production of sulphuric and phosphoric acids in the cel-lulose industry, in flue gas desulphurisation plants and also in the fertiliser industry, petrochemical indu-stry, fatty acid processing, the manufacture of acetic and formic acid, seawater desalination, in picklingplants and for heat exchangers that are operated with sea or brackish water.The weld metal is fully austenitic, and has distinct resistance to pitting and crevice corrosion in mediacontaining chlorides, high resistance to sulphuric, phosphoric, acetic and formic acid, as well as to seawater and brackish water. The high Ni-content leads to very good resistance to stress corrosion crackingwhen compared with the conventional 18/8 CrNi weld metal types. As a result of the high over-alloyingwith Mo as compared to 1.4539 or UNS N08904 it is possible to compensate for the demonstrably highsegregation rate of CrNi weld metals with a high Mo content.

DescriptionBÖHLER EAS 2 PW-FD is a strip alloyed flux cored wire with a rutile slag characteristic forposition welding of austenitic CrNi steels. The support provided by the fast-hardening slag allo-ws out-of-position welding with high current magnitudes and high welding speeds. The fine dro-plet, low-spatter, very powerfully welding spray arc, the reliable fusion penetration, the self-releasing slag and the effectively wetting seam formation result in a high weld quality at thesame time as short welding times. Additional advantages to its application result from the easeof handling, the low heat input due to the high welding speed, and the small amounts of clea-ning and pickling required. BÖHLER EAS 2-FD is preferred for flat and horizontal welding positions (PA, PB). The weldmetal is cryogenic down to -196°C and resists intergranular corrosion up to +350°C.

DescriptionBÖHLER CN 22/9 PW-FD is a strip alloyed, duplex steel rutile flux cored wire for position welding ofduplex steels in the chemical apparatus, plant and container construction, for chemical tankers and inthe offshore industry. The support provided by the fast-hardening slag allows out-of-position weldingwith high current magnitudes and high welding speeds. The advantage of the slag is its supporting effecton the weld pool. This permits, for example, welding with the stringer bead technique at a correspon-dingly high welding speed even in difficult pipe welding positions (5G, 6G). The fine droplet, low-spat-ter, very powerfully welding spray arc, the reliable fusion penetration, the self-releasing slag and theeffectively wetting seam formation result in a high weld quality at the same time as short welding times.The structure of the weld metal consists of austenite and ferrite (FN 30-50). The pitting resistance equi-valent is PREN ≥ 35 (%Cr+3.3%Mo+16%N). Testing the weld metal in accordance with ASTM G48Method A resulted in a CPT (critical pitting temperature) of 25°C. Also suited to joining different materi-als and to weld cladding. Usable between -46°C and +250°C.

2.7 Welding Consumables for Dissimilar Joints and Special Applications

ObjectiveThe materials used for welding engineering appear vast, confusing and com-plicated if one takes into consideration all the dissimilar weld joints that arepossible between the most varied types of steel. It is practically impossibleto record every individual combination of materials. The choice of filler metal must be emphasised as a crucial criterion. Thischoice must be made so that where possible the weld metal generated is nottoo hard, brittle and susceptible to cracks allowing for dilution with the diffe-rent parent metals. As a consequence of this, later sections of this manual set out general gro-und rules containing tips, recommendations and precautionary measures inthe form of broad guidelines which are to be considered when choosing fil-ler metals and welding technology. However, basic rules such as these mayonly be deemed of value if they can be implemented in practice with suffi-cient expertise and basic knowledge of metallurgy. This section describes filler metals that may be used for many different dis-similar welds or in the welding of problem steels.

2.8 Heat Resistant Welding Consumables

ObjectiveThis section contains product information for filler metals that are suitable forwelding heat-resistant steels.

Heat-resistant steels are used at temperatures over 550°C. In addition toscale-resistance and adequate high-temperature strength there is also arequirement for the lowest possible changes in volume during repeated hea-ting up and cooling down so that the oxide layers do not crack open.Furthermore they should also have adequate resistance to various annea-ling and furnace atmospheres.

The Cr, Si and Al alloying elements give rise to the scale resistance due tothe formation of dense and adhesive oxide layers. The Cr-Al alloy steels areferritic and less suitable for welding but are extremely resistant in sulphur-containing gases. The Cr-Ni-Si alloy steels exhibit an austenitic microstruc-ture, have excellent resistance in carburising furnace atmospheres contai-ning nitrogen but form a low melting point eutectic with nickel in sulphurousgases at approx. 700°C.

With these steels it is important to be aware of the embrittlement ranges400...500°C (with Cr contents above 15%) and above 950°C (grain growth)in ferritic steels and the σ-phase embrittlement between 650 and 800°C withCr contents above 20%.

2.9. Nickel-based Welding Consumables

ObjectiveThis section contains product information for nickel base filler metals. Themain applications of these filler metals are welding of nickel base alloys, hightemperature and creep resisting steels, heat resisting and cryogenic materi-als, dissimilar joints and low alloy problem steels.

Nickel and its alloys with Cr, Cu, Fe, Mo, Co, Al and Ti offer a broad and uni-versal range of possibilities for use, e.g. for highly corrosion resisting offsho-re constructions, chemical and petrochemical plant engineering, in flue gasdesulphurisation or for sea water desalination plants as well as for high tem-perature and heat resistant applications like the boiler fabrication or the con-struction of heating ovens and furnaces.

In addition some of the nickel base alloys are also suitable for cryogenicapplications down to -196°C.

The welding of nickel alloys

A brief overview of key specifics:

Cleanliness is a top priority. Weld edge and weld area must be free of anyresidues and in particular free of grease, oil and dust.

Oxide skin must be removed approx. 10 mm on each side of the weld.

The opening angle has to be wider than on C-steel, in general 60-70°. Tagwelding must be done in short intervalls. The root opening has to be 2-3 mm wide and the root face should be approx. 2 mm high.

Electrodes have to be re-dried prior to any welding.

For most applications we recommend string bead technic. When weaving,the oscillation should be limited to 2.5 x the diameter of the electrode corewire. This does not apply to vertical up welding.

The electrode should be welded with an angle of approx. 10-20° and the arcshould be as short as possible.

The end crater is to be filled and in the root to be grinded out. Ignition of anew electrode should be approx. 10 mm before the last end crater, then thearc has to be taken back to the end crater where the actual welding starts.The ignition points are then to be welded over again.

The interpass temperature should not exceed 150 °C and heat input shouldbe limited to approx. 8-12 KJ/cm.

If multi layer welding has to be made, each layer has to be cleaned with astainless wire brush to remove slag residues and oxide skins.

Weld surfaces can be cleaned by grinding, brushing with a stainless steelwire brush or by pickling.

DescriptionCore wire alloyed special stick electrode with special basic coating for high quality welded jointsof nickel-based alloys with a high Mo content (e.g. Alloy 625 and Alloy 825) and of CrNiMosteels with a high Mo content (e.g. 6% Mo steels). This type is also suitable for creep resistantand highly creep resistant steels, heat resistant and cryogenic materials, dissimilar joints andlow-alloy, hard-to-weld steels. Suitable for pressure vessel construction for -196°C to +550°C,otherwise with scaling resistance up to +1200°C (sulphur-free atmosphere). Because of theembrittlement of the base material between 600 and 850°C, use in this temperature rangeshould be avoided. High resistance to hot cracking, in addition to which the C-diffusion at hightemperatures or during heat treatment of dissimilar joints is largely inhibited. Extremely highresistance to stress corrosion cracking and pitting (PREN 52). Resistant to thermal shock, stain-less, fully austenitic. Low expansion coefficient between C-steel and austenitic CrNi(Mo) steel.Exceptional welding properties in all positions except for vertical down, good slag detachabili-ty, high resistance to porosity, notch-free weld seams, high degree of purity. The electrode andthe weld metal meet the highest quality requirements.

2.11. Welding Flux

ObjectiveThis section contains a brief description of the characteristic features of sub-arc welding fluxes from BÖHLER Welding.Basically the flux has decisive effect on the result of welding operations. Itsinfluence on the melting characteristics and various other physical propertiessuch as viscosity, surface tension, density, thermal expansion, and conduc-tivity in turn has a considerable bearing on the appearance of the bead sur-face and the slag removability.Another major consideration here is the influence which the flux exertsthrough the metallurgical reaction on the chemical composition, and thusalso on the mechanical properties of the deposit.

EN ISO 14174 differentiates 3 major types of flux:◆ F = fused ◆ A = agglomerated ◆ M = mixed

BÖHLER Welding offers agglomerated types only:◆ Aluminate-rutile: BB 305, BB 306◆ Aluminate-basic: BB 400◆ Fluoride-basic: BB 24, BB 24-SC, BB 202, BB 203, BB 418 TT,

BB 421 TT, BB 430, BB 444 and BB 910

DescriptionAgglomerated, fluoride-basic welding flux characterised by its neutral metallurgical behaviour and its highpurity. It also permits reliable welding with AC power, and is therefore suitable for the tandem method.The BÖHLER BB 24-SC allows the toughness achieved when welding with CrMo-alloyed wire electro-des to be brought to a higher level. Thanks to its very low P pick-up, this flux is also particularly suitablefor use in reactor construction and when welding hydrocrackers. In combination with the BÖHLER EMS 2 CrMo and CM 2-UP wire electrodes, very high toughness requi-rements at low temperatures can be met, even after a step-cooling treatment.

3.1 SELECTION GUIDE FOR HYDRO-ELECTRIC POWER STATIONS


3.2. Selection Tablesbase material oriented selection

OverviewThe selection range provided from the materials science point of viewattempts to respond to the behaviour of the base metal and matches the wel-ding parameters and the temperature input to this behaviour although choo-sing from the selection tables provides quicker and more direct access to theappropriate filler metals.

However, it has to be noted that this section does not go into detail about thewelding technology used for processing the filler metals listed. The appro-priate subsection of the next chapter or the individual data sheets of the fil-ler metals themselves should be referred to for this.

1) The material recommendations have been chosen in a way to ensure that the relevant filler metal is lower alloyed and thus tougher than the base metal.

2) The annealing temperatures have been chosen in a way to ensure that the lowest Ac1 temperature of the twomaterials involved is not exceeded. The annealing time depends on the relevant work piece thickness; it has tobe at least 15 minutes for thicknesses of 15 mm, at least 30 minutes for thicknesses of 15-20 mm and at least60 minutes for thicknesses above 30 mm. For work pieces of low thicknesses a medium annealing time shouldbe chosen, whereas in thick-walled components the surface should reach a temperature within the upper range.

In manual metal arc welding with covered electrodes, the coating fulfils the task of, on the onehand, creating a shroud of shielding gas and, on the other, of forming a slag in order to stopoxygen reaching the transferring drops of metal or the weld metal. The shield has an impor-tant effect on the welding properties and the mechanical properties of the weld metal, especi-ally at negative temperatures. In addition, the coating has an effect on positional weldability,on deposition efficiency, and on compensation for burn-off.

There are three main types of coating: rutile, basic and cellulose-coated stick electrodes, andmixtures of these types.

Rutile coated stick electrode (R)This type of coating is the one most widely used in practice. This is because it offers a rangeof advantages such as:• Very stable arc, making it easy for the welder to handle• DC or AC power can be used for welding• Good ignition and re-ignition properties• Suitable for all welding positions except for vertical down (PG) - depending on the

thickness of the coating and on the type of weld metal (high-alloy is restricted in the vertical-up (PF) and overhead (PD, PE) positions.

• Easy slag removal, finely structured, smooth seam, particularly for the thickly coated RR types (preferred for fillet welds and cover passes)

• No redrying is necessary (except for high-alloy)

The disadvantages of the rutile coated stick electrodes are:• Cannot be used for thick-walled and stressed components (more than 20 - 25 mm)• Inadequate impact energy at negative temperatures• Higher hydrogen content (20 ml/100 g weld metal)• Cannot be used for higher-carbon steels (C < 0.2%)

Basic coated stick electrode (B)Basic coated stick electrodes feature excellent toughness, in particular in the low temperatu-re range. Other advantages include:• Extremely low hydrogen content (< 5 ml / 100 g).• No restriction on wall thickness• Can be used for all welding positions other than vertical down (PG);

basic vertical down electrodes are also suitable for this position• Also suitable for welding higher-carbon steels (C > 0.2%).

Selection guide


3-33

Disadvantages include:• Unstable arc, therefore somewhat more difficult for the welder to handle• In some cases can only be welded with DC• Less favourable slag removal and a seam surface with a coarser structure• Sensitive to the absorption of moisture; basic stick electrodes must be redried before

welding (except for high-alloy). Stick electrodes that are vacuum packed or packed in sealed tins can be used for welding without redrying, but should be used from a heated quiver after the packaging has been opened.

The double-shell electrode is a special variant of the basic stick electrode. It is a stick electrodewith 2 coatings: the material of the inner coating is primarily rutile, which ensures fine drop trans-fer and a very well aligned arc. The outer coating consists primarily of basic materials, whichensure that the weld metal has good toughness (at low temperatures) and resistance to cracks.

Cellulose coated stick electrodes (C)This type of coating was specially developed for vertical down welding on large pipelines. Thehigh proportion of cellulose in the coating leads to an arc that is highly stable and intense. Thisensures reliable root formation even at high welding speeds or with larger electrode diameters.

The high economy is a result of the use of electrodes with large diameters for the root, filler andcover passes, which can be carried out with high currents and at high welding speeds. Becausethe weld metal has a high hydrogen content, application is restricted in terms of wall thicknessand the required impact energy.

Mixed types (RC, RB)In addition to these three important main types, a large number of what are known as "mixedtypes", such as the RC and RB coatings, are also available. These attempt to combine the lar-gest possible number of positive properties in one stick electrode.

RB types (rutile with basic components) are often used for root and pipe welding because of theirgood gap bridging and properties suited to out-of-position welding.

RC types are universally applicable and, thanks to their cellulose content, can be used in all wel-ding positions including vertical down (PG).

Coated stick electrodes can be used universally on all materials that can be welded. Not a lot ofequipment is required, although, due to the low deposition rate, the economy of this methodmust be considered low.

In the TIG method, a burning arc is used as the source of heat under the protection of an inertgas. Tungsten rods, pure or alloyed, are used as the electrode.

The shielding gas consists of argon, helium, or of mixtures of argon and helium. The shieldinggas serves a number of purposes here. It protects the extremely hot tungsten electrode fromoxidation by atmospheric oxygen, cools it, and permits the formation of a stable arc. At thesame time, the liquid metal pool and the melting filler wire are protected from the atmosphe-ric air.

In TIG welding, the welding consumable is supplied, without current, at the side of the moltenpool. For manual welding, the consumable material is supplied as sticks with a length of 1 m,and as wire rolled onto spools for TIG cold wire welding by machine. TIG hot wire welding isa further variant, in which the filler wire is heated, using electrical resistance heating, as it issupplied, in order to increase the deposition rate.

In the case of steels and nickel-based alloys, welding is carried out almost exclusively withDC, the electrode being on the negative pole. Guide figures are provided in the following table,indicating how much current the tungsten electrode can carry, according to the diameter:

The MIG/MAG process is a form of gas shielded arc welding by machine, in which the arc burnsunder shielding gas between the wire electrode, which carries the current, and the workpiece. Awire electrode, supplied from a roll by machine, acts as the electrode and melts in its own arc.

Argon, helium, or mixtures of these gases, are used as the shielding gas in the MIG process. In theMAG process, shielding gases of argon with the addition of oxygen, helium with added oxygen, car-bon dioxide (CO2), or mixtures of these gases are used. The shielding gas allows a stable arc tobe formed, and prevents atmospheric air from reaching the liquid weld pool. The addition of someoxygen to the shielding gases reduces the surface tension of the molten pool, resulting in the for-mation of a smoother seam surface and good transitions to the edges of the seam. In addition, thetransfer of material within the arc occurs with finer drops.

The resulting burn-off of alloy components is compensated for through appropriate over-alloying ofthe wire electrodes. It is essential to make sure that the welding area is free from draughts. Whenwelding speeds are high and with rapid weaving, it is necessary to make sure that the liquid weldpool is properly screened by shielding gas through the use of a suitable quantity of shielding gasand the right nozzle shapes.

Only DC converters or rectifiers can be used as the source of current. The electrode is usually onthe positive pole.

Summary of the various types of arc used for MIG/MAG welding

3.3.3. Gas shielded metal arc welding(MIG/MAG process)


Arc type Application Material transfer Spatter formation Comments

Short arcWelding with a short arc is preferably done using wires with diameters 0.8 - 1.0 mm, in some casesalso using dia. 1.2 and 1.6 mm. This method requires the use of a suitable current source with anadjustable no-load voltage and, in some cases, also with an adjustable characteristic curve.Depending on the diameter of the wire, the arc voltage is between 14 and 22 V, with currents ofbetween 60 and 200 A.

Transitional arcWith a transitional arc, the transfer of material takes place in an irregular sequence, both with andwithout short circuits. As a result, the tendency for spatter to adhere to the workpiece is increased.Because its performance is higher than that of the short arc, transitional arc welding is used for thefiller and cover passes in medium plate thickness, and in some cases also for vertical down welding.

The following table contains guide figures for current, voltage, wire feed rate and the deposition ratefor the transitional arc.

Long arc (only under CO2 and shielding gases with more than 20-25% CO2)The term long arc is used for drop transfers in which free transfers and short-circuit transfers aremixed. The drops are larger than with the spray arc. A long arc is formed when welding with carb-on dioxide or mixed argon gases with more than 20% carbon dioxide. Since the drop transfer takesplace partly with short circuits, larger spatter losses can occur.

In the upper performance range, the field of application of the long arc is similar to that of the sprayarc. In the lower to medium performance range, it can often also be used for out-of-position wel-ding. Vertical down seams can be reliably welded, above all using the CO2 arc. As the proportionof carbon dioxide in the shielding gas rises, so do the resistance to porosity and the reliability ofthe fusion penetration. The application of the long arc is strictly restricted to welding of unalloyedand low alloy steels.

Spray arc (only under argon-rich shielding gases with more than 80% Argon)Welding with a spray arc is primarily done using wires with diameters 1.0 to 1.6 mm, in some casesalso using 0.8, 2.0 and 2.4 mm. The main field of application is normal joint welding of workpiecesmore than 4 mm thick, and in build-up welding applications.

In spite of the higher price of the wire, the small wire diameter brings economic advantages, since,as a result of the higher specific current density in the wire electrode (up to 300 A/mm²), the depo-sition rate at a given current magnitude and arc voltage is noticeably increased.

Mixed gases generally result in a material transfer with finer drops, and therefore to a more stablearc, as well as to reduced spatter formation. The spatter can, moreover, also be reduced bykeeping to the lower limit of the arc voltage.

Selection guide

Since the weld pool is significantly cooler, thin plate with thicknesses of 0.8 mm upwards can easi-ly be welded. As a result of the exceptional gap bridging, and since the rear of the root is smooth,this method is also used for root welding at greater wall thicknesses, and for out-of-position welding.

The following table contains guide figures for current, voltage, wire feed rate and the deposition ratefor the short arc.


3-37

The following table contains guide values for the current, voltage, wire feed rate and deposition rateof various wire diameters for carbon and low-alloy steels. Medium values are selected for manualwelding, whereas the higher values are used for machine welding. The current should be set 10 - 15% lower for austenitic wire electrodes.

An extension to welding with a spray arc is welding with the addition of a cold wire that carries nocurrent. A second wire, without current, with a diameter 1.6 mm or 2.4 mm, is introduced from theside into the arc. The deposition rate is increased by up to 80%, and the melting losses and fusionpenetration are significantly reduced. This is advantageous for build-up welding. The method hasalso proven effective for filling large seam cross sections.

Pulsed arcWith the pulsed arc it is possible to achieve short-circuit-free, low spatter release of the drops fromthe wire electrode. This is also achieved at low arc powers, which otherwise would lead to shortarcs (or even long arcs) and thus to short-circuits with spatter formation.The welding current is pulsed, and the following processes thus occur in the welding:

• The arc burns at a small background current intensity, melting the wire electrode and the base material.

• An increased pulse current overlays the background current, releasing one or more drops that transfer, without short-circuit, to the weld pool.

• The magnitude of the current falls back to that of the background current, the arc burns until the next current pulse.

• The number of drops can be controlled selectively through the pulse frequency.

The pulsed arc technique allows thicker wire electrodes to be used, which therefore are easier tofeed. Depending on the particular application – thinner (from 2 mm upwards) or thicker plate – root,filler or cover pass welding – out-of-position – the pulse frequency can be changed to achieve opti-mum parameters with spatter-free drop transfer.

Argon-rich mixed gases with a maximum of 18% carbon dioxide can be used as the shielding gas.The particular advantages of the pulsed arc are found with materials such as aluminium or nickel,and with corrosion-resistant chromium or chromium-nickel (molybdenum) steels. Due to the con-trolled heat input, welding on high-strength fine-grained structural steels or low-temperature steelsis also effective.

Shielding gasesThe choice of the shielding gas is determined by the alloys of the materials to be welded and by therequirements placed on the quality of the seam and the freedom from spatter. Carbon dioxide (CO2)is primarily used for welding unalloyed structural steels and for armouring against wear.

Mixed gases are preferred for welding unalloyed and low-alloy steels, such as the creep-resistantsteels used for the manufacture of boilers and pipelines. The high quality of the seams, the good, evenfusion penetration and substantial freedom from spatter satisfy the requirements placed on high qua-lity welds.

Argon, with the addition of 1 - 5% oxygen or of 2 - 3% CO2 are primarily used for welding high-alloyferritic and austenitic welding consumables. The melting losses of the alloy components is lower thanis the case with mixed gases and carbon dioxide, while the material transfer occurs with very finedrops and is almost free of spatter.

Welding with flux cored wires, like welding with a solid wire electrode, is a metal-arc welding pro-cess with a melting electrode, and the two are therefore basically comparable. Whereas solid wiresalways demonstrate a similar melting characteristic, depending on the selection of welding para-meters, the welding properties and the deposition rate, the suitability for various positions, and themechanical properties obtained when using flux cored wires are, however, strongly influenced bythe powder filling.There are gas-shielded flux cored wires for which the shielding gas must be supplied from outside,as well as self-shielding wires which generate their own shielding gas in the welding process.Böhler Welding offers 2 self-shielding flux cored wires, particularly for the vertical down position onpipelines:• Pipeshield 71 T8-FD for pipe steels up to API X60 (L415NB/MB) (Ni < 1%)• Pipeshield 71.1 T8-FD for pipe steels up to API X60 (L415NB/MB)• Pipeshield 81 T8-FD for pipe steels up to API X70 (L485MB)Amongst the gas shielded flux cored wires, we distinguish 2 types of flux cored wire: metal powderand slagging rutile or basic flux cored wires.

The core of the metal powder flux cored wires primarily consists of metal alloys, iron powder andelements that stabilise the arc. The surface of the weld seam is without slag, although isolatedislands of silicate are possible, depending on the shielding gas and on the base material. The mate-rial transfer takes place in fine drops, and with little spatter. The current carrying capacity and thedeposition rate are high. The arc is wide, stable, and has very good gap bridging capability. Theability to process with a short arc is very good, with or without pulses, and it is well-suited to auto-matic welding processes. PA, PB and PC are the preferred welding positions.

The following metal cored wires are found in the Böhler range:

The core of the slagging flux cored wires primarily consists of slag-forming materials, metal alloys,iron powder and elements that stabilise the arc. Amongst the rutile flux cored wires, we distinguish2 types:• with a fast solidifying slag, the P-type (according to standard) for all positions apart

from vertical down• With a slow solidifying slag, the R-type (according to standard) for the

PA, PB and PC positions

Selection guide

The basic flux cored wires only include the type with a slag that solidifies at normal speed. Bothtypes of the high-alloy rutile flux cored wires, i.e. those with the fast and slow solidifying slag, areused; the reason for this is the better surface of the seam obtained from the type with the slow soli-difying slag.

The unalloyed, creep resistant and higher-strength flux cored wires are usually of the fast solidify-ing type. The advantage of the type with the fast solidifying slag derives from the supporting effectof the slag, making it possible to use higher currents. The arc of the rutile flux cored wires is softand very stable, and the material transfer takes place with very fine drops and little spatter. As aresult of the shielding effect of the slag as the material is transferred, M21 (15-25% CO2) can alsobe used as the shielding gas for high-alloy flux cored wires. Rutile flux cored wires only weld in thespray arc range; root welding is only possible with a backing.

Basic flux cored wires can also be used for welding in all positions, although the highly fluid slagprovides no support, so that welding in difficult positions (PF, PD, PD) can only be done with a redu-ced current. The material is transferred in fine to medium sized drops, root welds can be done withor without backing. The main advantage of these flux cored wires lies in the weld metal which iscrack-resistant and tough even at negative temperatures, allowing any wall thickness to be welded.Basic flux cored wires can also be used to weld with a short arc, with or without pulse.

It is a feature of all flux cored wires that, as a result of the wide arc, gap bridging is better and therisk of lack of fusion is lower than with solid wire electrodes. The likelihood of pores is also lower.Thanks to the wider parameter window (the range of voltages and currents within which the elec-trode can weld with little spatter), the working range without having to change to a different wirediameter is greater. Drops are transferred with little spatter, and the process stability is high.Because of the faster melting of the flux cored wire, and the high current carrying capacity, the pro-cess is economical. In difficult positions the effect of the fast solidifying slag also contributes. A fewpractical notes on welding with flux cored wires follow:

• Flux cored wires melt faster than solid wire electrodes. The wire feed rate and the welding speed must therefore be increased.

• Flux cored wires need more shielding gas; the flow rate is about 15-18 l/min.• When using metal cored wires the torch can be carried trailing, leading or neutral.

Welding at a leading angle results in a flatter weld bead and less fusion penetration.• Slagging flux cored wires must always be used at a trailing angle.• The wire feed mechanism should have smooth drive rollers; a 4-roller drive is helpful.

The contact pressure should not be set too high, as the flux cored wire can easily be deformed.• Provide suction for the fumes. The smoke generated by slagging flux cored wires is greater than

with solid wire, and is similar with metal cored wire.

Submerged arc welding requires a welding consumable (wire, strip or flux cored wire) and a non-metallic auxiliary material, the welding flux.

The welding flux has a very significant effect on the resulting weld. As a result of the melting beha-viour and of various physical properties such as viscosity, surface tension, density, thermal expan-sion and electrical conductivity it has a very strong effect on the appearance of the seam and onthe slag detachability.

The effect of the welding flux, through the metallurgical reaction, on the chemical composition andtherefore the mechanical properties of the weld metal is of great importance.

Depending on the method of manufacture a distinction is made between:Fused flux, code F (fused)

Made by melting in an electric arc furnace; homogenous, not sensitive to moisture, resistant to abrasion, but a very limited metallurgical reaction, high apparent density and relatively poor slag detachability.

Agglomerated flux, code A (agglomerated), e.g. BÖHLER BB 24.Manufactured through agglomeration followed by drying in a rotary kiln; very good metallurgical reaction, low apparent density, good slag detachability, possibility of additional alloying, but sensitive to moisture and abrasion.

According to the basicity, the welding flux is classified into acid, neutral and basic welding flux. Thebasicity is calculated from

basic constituents (CaO, CaF2, MgO, MnO)B =

acid constituents (SiO2, TiO2, ZrO2)

If B is less than 1 we speak of an acid welding flux (predominantly acidic constituents); at a valuebetween 1 and 1.2 it is considered neutral; above that we speak of a basic welding flux, and above2 of a highly basic welding flux.

The following fluxes are in common use, classified according to their main constituents:

Manganese silicate types (MS), predominantly MnO and SiO2.

Calcium silicate types (MS), predominantly CaO, MgO and SiO2.

Aluminate rutile types (AR), predominantly Al2O3 and TiO2.

Aluminate basic (AB), predominantly Al2O3, CaO and MgO

Fluoride basic (FB), predominantly CaO, MgO, MnO and CaF2

Other flux types are defined in the EN ISO 14174 standard.

Each type of flux has its own specific properties that must be taken account when making the sel-ection for practical application.

OverviewThe biggest problem in the selection of welding consumables is that of cor-rectly assessing the metallurgical behaviour of the materials that are to bewelded.

The whole welding technique, preheating, and any subsequent heat treatmentthat might be necessary all revolve around this.

This section attempts to discuss the most important technical welding aspec-ts of various typical materials groups in a few relatively brief chapters. As faras possible, a general outline will be given of the required welding technique.

The last chapter in this section approaches the altogether more complex pro-blem of dissimilar joints. Since a detailed treatment would be the size of abook, this chapter just contains short notes on how various combinations oftypical groups of materials are to be treated.

The following factors are the main influence on the welding suitability of the steels: composition,manufacture, treatment and physical properties. The composition is of central importance, as thisis the main thing that determines the strength and the deformation properties.

Suitability of unalloyed steels for weldingLeaving aside the phosphorus and sulphur content, the suitability of unalloyed steels for welding ismainly judged according to the carbon content. As a result of the welding heat, part of the basematerial is austenitised at the edge of the welding seam. Following the rapid cooling immediatelyfollowing the weld, local hardening and hydrogen embrittlement can occur in the affected zone.Unalloyed steels with carbon contents up to about 0.22% can usually still be welded without diffi-culty; at higher-carbon levels and Mn contents of above 1%, base materials with a wall thicknessof about 20 mm or more must be preheated, in order to reduce the cooling speed involved in theaustenised conversion. Steels with a C-content of more than about 0.5% are generally not consi-dered suitable for welding. Nevertheless, the carbon content alone is not sufficient to determine thesuitability of unalloyed steels for welding. Welding difficulties can occur as a result of higher hydro-gen, nitrogen and oxygen contents, as well as due to the presence of strong segregation. Wallthickness and the stress level also play an important role.

Suitability of alloyed steels for weldingSteels with alloy contents up to 5%According to their properties when in use, these steels are divided into, for example, creep resi-stant, high-strength and cryogenic. The steels often require appropriate heating prior to, during andafter welding if usable welded joints with particular properties are to be achieved. The chemicalcomposition in terms of the type and quantity of alloying constituents, and the microstructure, areimportant. Higher strength quenched and tempered steels usually have C-contents between 0.2 and 0.6%. Chromium, nickel and molybdenum are important alloying elements, and so aremanganese, silicon and vanadium.

Their increased tendency to form martensite leads to higher tensions in the component as the weldseam cools. The critical cooling rate is less, which means that it is possible for hardened micro-structures to form even under air cooling, and this can impair the ability of the welded joint todeform. There is a high risk of hardening cracks in the transition zones. On the other hand, due tothe tempering effect, zones with marked softening can also occur. Since there are no same-typewelding consumables for these steels it is not generally possible to create joints with the propertiesof the base material.

Steels with alloy contents > 5%The stainless steels, containing either simply chromium or both chromium and nickel as the cha-racteristic alloying elements, constitute an important group.

The chromium steels are mainly divided into types with ferritic or with martensitic microstructures,which are classified as having only limited suitability for welding. The reason for this is the tenden-cy of the ferritic chromium steels to form coarse grains, or the tendency of the martensitic chromi-um steels to harden in the heat affected zone of the base material.

In contrast, the austenitic CrNi(Mo) steels are well-suited to welding. However, if they are not pro-perly processed, the corrosion resistance, hot cracking resistance and toughness of these steelscan be negatively affected. Certain basic rules must therefore be followed when welding stainlesssteels.

3.4.1. Welding suitability of the steels

Selection guide


3-45

Structural steels are low carbon steels with a specified carbon equivalent value (CEV) in which thecarbon content lies between 0.10 and 0.60%. The steels coded with S, such as S185, S235JR+ARand S355J2+N, are used in steel construction, while those coded with E, such as E292, E335,E360, are used in mechanical engineering. The structural steels are standardised in EN 10025-2.Structural steels are either hot formed in the production condition (AR=As Rolled), normalised (N)or cold formed. In most cases the mechanical properties are adequate. Structural steels can bewelded, and can be stress-relieved.

The weldability of structural steels identified as S185, E295, E335 and E360 is limited as their car-bon content is either not specified (S185) or is too high (E295, E335, E360), and must not be usedin steel constructions that are subject to acceptance tests.

Fine-grained structural steels are steels with a fine-grained structure (ferrite grain size ≤6), a carb-on content of at most 0.20%, a limited carbon equivalent value, as a result of which they have verygood welding properties. Their toughness, including at low temperatures, is improved over structu-ral steels, and they are resistant to ageing.

Only the unalloyed fine-grained structural steels with a minimum yield strength of 275-460 MPa areconsidered in this chapter. They are either normalised, or are normalised rolled (code N) as stan-dardised in EN 10025-3, or thermomechanically rolled (code M) as standardised in EN 10025-4.

The cryogenic variant of the fine-grained structural steels, with the additional code L, can be useddown to -50°C. Without additive, use is limited to -20°C. Sufficient low-temperature toughness musttherefore be attended to when selecting the welding consumables.

The welding of higher-strength fine-grained structural steels is treated in a chapter further below.

Welding unalloyed structural and fine-grained structural steelsAs a rule, the same mechanical and technical properties are expected from welding consumablesused for a welded joint as are found in the corresponding base material. As the carbon contentrises, the suitability of the steel for welding falls due to hardening. In the case of steels whose sui-tability for welding is not certain, corresponding measures therefore have to be taken in order toavoid unacceptably high levels of hardening and the cracks that result. Options for predicting thetendency to hardening include the carbon equivalent value, as well as the TTT curves and the wel-ding TTT curves. If necessary it is also possible to carry out a practical welding test followed by anexamination of the microstructure or by hardness tests. As a rule of thumb, it can be said that thehardening in the transition zone of unalloyed structural steels should not exceed 350 HV (Vickershardness units).

Welding technology for unalloyed structural and fine-grained structural steels:The welding consumables are to be selected in accordance with the minimum requirements for themechanical properties of the base material.

Steels with "guaranteed welding suitability" and with wall thicknesses of 30 mm or even 20 mmupwards – depending on strength – should be preheated to 100 - 150°C; if stick electrodes areused, they should only be basic types. Steels with only "limited suitability for welding" shouldalways be preheated in line with the carbon equivalent value, and only basic, redried welding con-sumables should be used.

Strength [MPa] Thickness limit [mm]up to 355 30> 355 - 420 20

Selection guide

As the component becomes thicker, the internal stresses caused by the local heating and coolingcan reach the yield strength and can exceed it when the operating stresses are added on top. Theresult is cold deformation, ageing and embrittlement. For this reason, steels with guaranteed sui-tability for welding should also be preheated above a certain wall thickness.

The following limits to reliably weldable wall thickness, depending on the strength, provide a guide:

Walls thicker than this always require preheating to 100 - 150°C. (See also the Notes on PreheatingMaterials chapter for information about preheating)

Oil and natural gas are at present the most important sources of energy. Massive transport pipeli-nes either already exist or are in the project planning stage around the world. The development ofnew, higher-strength tube steels is now putting tighter requirements on the welding technology.Thanks to our specially developed electrodes, which are ideally matched to individual steels, wecan fully satisfy these requirements as well as the strict safety regulations.

In most cases, the circumferential pipe welds are manufactured as vertical down welds using cel-lulose coated stick electrodes. The progress of construction largely depends on the speed withwhich these seams can be fabricated. This method makes it possible to weld using an electrodewith a larger diameter, higher currents and higher welding speeds. This brings significant economicadvantages when compared with the otherwise usual welding of a vertical up weld using rutile orbasic coated stick electrodes.

Welding with basic coated stick electrodes, both for the vertical up and vertical down positions, istreated below in the "Welding with cellulose coated stick electrodes" section. Böhler Welding offersa complete range of types for exceptional low temperature stress.

* Only for root welding

The special suitability of the BÖHLER FOX CEL electrodes for root welding even of high-strengthsteels is particularly worth noting. Through the use of BÖHLER FOX CEL for the root and, if neces-sary, for the hot pass, in the form of what is known as "combination welding", the welding techno-logy developed by Böhler Welding provides the greatest security against cracks.

It is of great importance to carefully prepare the seam if a perfect welded joint is to be achieved.Close tolerances cannot generally be achieved with flame-cut edges. In practice, the pipe ends areusually prepared by machining.

In order to avoid pores and lack of fusion, the edges of the seam must be free from foreign mate-rials such as oil, lubricant, scale or dirt. Scoring and notches also upset the handling of the elec-trode. The BÖHLER FOX CEL Ø 2.5 or Ø 3.2 mm electrode is recommended for the root pass onpipes with a smaller diameter (up to 250 mm).

Preheating and interpass temperaturePreheating the base material promotes or accelerates the effusion of hydrogen, so counteringhydrogen-induced cracking. Furthermore, depending on the temperature and on the chemical com-position of the steel, hardening in the heat affected zone can be reduced.

The preheating and interpass temperatures can be found in the corresponding datasheets, or inChapter 2.3. Preheating should always be carried out for walls thicker than 20 mm, regardless ofthe C-content. It is helpful to increase the temperature to about 150°C for higher-carbon steels thatare susceptible to hardening. The external temperature must also be taken into account!

The pipe ends of thin pipe materials that do not tend to harden should be slightly warmed up to atleast 50°C in order to remove water condensation. The various specifications permit different car-bon contents. If the C-content is above 0.20%, we recommend that you consult the manufacturerof the electrode or of the steel in order to select the preheating temperature.

The interpass temperature affects the metallurgical processes that take place during the solidifica-tion and cooling, and therefore has an effect on the mechanical properties of the weld metal. Therate of hydrogen effusion is also affected.

It is recommended that when basic coated stick electrodes are used, the interpass temperatureduring the welding is kept to at least 80°C.

Specific investigations are carried out in order to recommend the preheating and interpass tempe-ratures for cellulose coated stick electrodes, and these closely match with users' practical experi-ence. These are presented in Chapter 2.3.

Welding with basic coated stick electrodesIn some countries, the use of basic coated stick electrodes in pipeline construction is preferred, for a number of reasons, to the use of cellulose coated stick electrodes. The use of basic electro-des is generally recommended for welding very thick steels, susceptible to hardening, of more than 25 mm. The reason for this is the very low amount of hydrogen produced by these types of electrode.

The high heat dissipation resulting from the thick walls, together with the simultaneous presence ofhigh levels of hydrogen when cellulose coated stick electrodes are used, intensifies the risk thathydrogen-induced cracks will form.

Vertical up weldingThe use of basic coated stick electrodes of the FOX EV 50 (E7018-1), FOX EV 60 (E8018-C3),FOX EV 65 (E8018-G) types, and particularly the FOX EV PIPE (E7016-1), FOX EV 60 PIPE(E8016-G) and FOX EV 70 Pipe (E9016-G) types, which are been specifically optimised for pipewelding, is preferred.

It is necessary to ensure that the electrodes are protected from moisture. Electrodes from boxesthat have already been opened must be redried, in accordance with the specifications, for 2 hoursat 300 - 350°C before they are used.

The root pass is usually carried out using an electrode with adiameter of 2.5 mm, or, if the FOX EV Pipe series is used, ofdiameter 3.2 mm, in order to achieve proper through-welding.Welding is carried out upwards, with a root gap of about 2.5 - 3 mm. In order to save weld metal on wall thickness of>20 mm, a special form of seam may occasionally be used.

Welding the filler and cover passes is usually carried out usingelectrodes with diameters of 3.2 and 4 mm. The welded jointmust be protected against wind, rain and so forth in order toavoid pores.

Performing the weldingJoint preparation: The joint is prepared by machining. The permissible dimensional tolerances of

the tubes are listed in the API spec. 5L and EN 10208-2 standards.

Centring the tubes: As when welding with cellulose coated stick electrodes, the tubes are centred using hydraulically operated internal centring gear. Due to the relatively strong forma-tion of the root pass, and due to the low level of hydrogen introduced by the basic coated root electrode, the internal centring gear can be removed, provided there is no excessive edge displacement, as soon as the root pass has been finished.

Welding at low external temperatures or in wet weatherIn unfavourable weather, particularly if the air temperature is less than 0°C, welding work may onlybe carried out on pipelines if the welding and working conditions allow the seam to be created pro-perly. This means that although it is not forbidden to weld when the external temperature is low,certain precautionary measures must be taken.

The following rules have been found effective in practice:

1. Remove ice, frost and water by preheating.

2. Weld quickly without extended breaks, if necessary using a number of welders for one seam.

3. Use the thickest possible electrodes.

4. The welder himself must be sufficiently well protected from the cold (if necessary provide tents, wind protection or infrared heaters).

There are no generally applicable rules or restrictive specifications about carrying out welding workin the rain or on wet workpieces. Nevertheless it goes without saying that the welding area and itssurroundings must be protected from rain and other bad weather. Under all circumstances, the wel-ding area must be free from water.

Redried basic stick electrodes have in any case very little hydrogen in the weld metal, and there-fore offer better security, under unfavourable conditions, against hydrogen-induced cracking.However, if welding is carried out in a water saturated atmosphere, even the basic weld metal cancontain significant amounts of hydrogen.

3.4.4. High-strength fine-grained structural steels

Selection guide

The micro-alloyed steels can be divided into three main groups, according to how they are manufactured:

1. normalised fine-grained structural steels2. thermo-mechanically treated fine-grained structural steels3. quenched and tempered fine-grained structural steels

In fine-grained structural steels, the loss of strength resulting from the low carbon content is com-pensated for via microalloying elements such as Al, Nb, Ti and V. Through the addition of Cr, Moand Ni together with quenching and tempering, 0.2-offset yield strengths of 1300 MPa can beachieved while retaining good toughness and welding properties.

Conventional, rolled, normalised fine-grained structural steels can be made with 0.2-yield limits ofup to 460 MPa. The properties are achieved through the addition of microalloying elements.

In thermo-mechanically rolled steels, the strength is achieved through the addition of microalloyingelements and through rolling processes with careful temperature control. This allows 0.2-offsetyield strengths of 960 MPa to be achieved. The strength properties achieved through a thermo-mechanical treatment cannot be repeated.

0.2-offset yield strengths of up to 1300 MPa are achieved with quenched and tempered fine-grai-ned structural steels. The strength is achieved through microalloying elements, the addition of Cr,Mo and sometimes of Ni, and by a quenching and tempering process following rolling.

Welding fine-grained structural steelsThe generally applicable and recognised rules for welding low-alloy, higher-strength fine-grainedstructural steels meeting EN 1011-2 must be followed.

It is generally necessary to ensure that as the minimum values of the 0.2-offset yield strengthincrease, and as the walls become thicker, greater care must be taken during processing, while adesign that is appropriate for welding and for the stresses to which it will be subjected is an impor-tant prerequisite.

The risk of hot cracking is low in these steels. On the other hand, the possibility of lamellar tearingmust be countered by design and/or by the welding technique (reducing internal stress, prehea-ting). At the same time, excessive hardening must be avoided, and the hydrogen content kept aslow as possible in order to minimise the risk of cold cracking.

The preheating temperature depends on the thickness of the workpiece and on the chemical com-position of the base material and the weld metal, the energy input per unit length, and on the expec-ted internal stresses. As the thickness increases, the upper range of temperatures should be aimedat. The values of the thickness limit for preheating, depending on the minimum value of the 0.2-off-set yield strength of the base material, are contained in the following table.

The temperature-time curve during welding is of crucial significance to the mechanical propertiesof high-strength welded joints. In particular, this is affected by the plate thickness, the shape of theseam, the energy input per unit length, the preheating temperature, and the layer structure.

In order to characterise the temperature-time curve during welding, the cooling time t8/5, i.e. the timetaken for a weld bead to cool from 800 to 500°C is usually selected. The cooling time t8/5 in any par-ticular case depends on the requirements for the strength of the particular welded joints after anypossible heat treatment has been carried out. A combination of welding current, arc voltage, wel-ding speed and preheating temperature that is appropriate for the cooling time t8/5 to be applied isspecified by the user in light of economic and production engineering factors.

The selection of a suitable welding consumable is a further key factor that determines quality.

Welding technology

◆ Welding consumables are to be chosen that demonstrate a controlled, diffusible hydrogencontent, such as basic coated stick electrodes, basic flux for submerged arc welding, basic ormetal cored wires and solid wire electrodes.

◆ The preheating and interpass temperature depends on the wall thickness, the chemical com-position of the base material and of the weld metal, the energy input per unit length and on theexisting internal stresses.

◆ The temperature-time curve (t8/5) it of great significance for the mechanical properties of thewelded joint. It is essential that the recommendations regarding heat input from the manufactu-rer of the base material and of the welding consumable are observed.

The large scale industrial use of oxygen in the steel industry, nitrogen in the chemical industry, andthe supply of natural gas to all industrial sectors, have become much more important in recentyears. With the increased use of these gases, their economical transport and storage has becomemore and more important. The behaviour of gases, which change to a liquid state at low tempera-tures and so greatly reduce their volume, is exploited here.

This property of gases can only be used if suitable base materials and welding consumables, whichhave sufficiently good mechanical properties and are adequately tough at the low temperatures ofthe liquid gases, are available for the construction of the necessary transport and storage contai-ners.

Unalloyed, low-alloy or high-alloy steels that remain tough at low temperatures (e.g. below -50°C)are known as low-temperature steels. Unalloyed and low-alloy steels can in any case be used attemperatures down to -50°C.

These groups of steels can be distinguished:

1. Unalloyed or low alloy, low-temperature and fine-grained steels for operating temperatures down to around -50°C in a normalised state or down to about -60°C in a quenched and tempered state.

2. Nickel alloy quenched and tempered steels with between 1.5 and 9% nickel for operating temperatures between -80°C and about 200°C.

3. Austenitic chromium-nickel steels for operating temperatures down to about -269°C.

Welding low-temperature steelsThe characteristic property of welding consumables for welding cryogenic materials is their abilityto change shape at low temperatures. This is usually tested using the Charpy impact test. Thevalue of the impact energy allows conclusions to be drawn about the tendency to brittle fractureand the possibilities of use down to a particular temperature.

The value of 27 joules with the Charpy V sample is often taken as the minimum value for the impactenergy at the lowest operating temperature concerned.

When welding the low-temperature and fine-grained structural steels, controlled heat input must beensured in order to keep the zone affected by the heat as narrow as possible and yet to avoidhardness peaks. Unalloyed and low-alloy basic coated types according to EN ISO 2560 and EN ISO 18275 are used for the stick electrodes. It is necessary to ensure that the hydrogen con-tent of the welded joint is as low as possible in order to avoid cold cracking, which means that redry-ing the electrodes before welding, and taking them from a heated quiver, is to be recommended.

This point also applies to the welding flux used in submerged arc welding. The necessary low-tem-perature toughness and strength must be taken into account particularly when selecting wire-fluxcombinations or wire-shielding gas combinations.

When unalloyed flux cored wires are used, basic or metal cored wires are to be preferred becau-se of the toughness and the low diffusible hydrogen content.

3.4.5. Low-temperature steels

Selection guide

When welding nickel-alloyed quenched and tempered steels, same type or similar type weldingconsumables containing between 2.0 and 3.5% Ni are used. Same-type welding consumables arepreferred if, in addition to the necessary minimum temperature, the mechanical-technological pro-perties (strength, toughness) and the physical properties (coefficient of thermal expansion) of thebase material must be provided in the welded metal.

Welding consumables with higher nickel contents have a greater tendency to hot cracking.Although it is possible to weld the 5% nickel steels using austenitic welding consumables such as"A 7" or "ASN 5", the use of nickel-based types is preferred for this base material. Heat treatmentof the welded joint must then be omitted, in the light of the austenitic weld metal (embrittlement,carbon diffusion).

The 9% Ni steel is normally joined using nickel-based welding consumables. These nickel-basedtypes have advantages over conventional austenites, due to a higher yield strength and the possi-bility of giving heat treatment to welded joints. They can also be used for steels with a low nickelcontent.

With a limited dilution with the base material, resistance to cracking and adequate low-temperatu-re toughness down to -200°C is achieved.

Same type welding is used on the austenitic chrome-nickel steels for low-temperature applications.



3-54

The strength of the unalloyed structural steels falls significantly at high operating temperatures;they can therefore only be used up to a temperature limit of about 350°C. Creeping and flowingprocesses occur in the steel under high-temperature stress, which make the permissible load beco-me time-dependent. For that reason the design of components for operating temperatures aboveabout 550°C is carried out using the creep strength, from which it is possible to see how long thematerial can support a particular stress at a particular temperature before fracturing.

Creep resistant steels therefore have sufficient mechanical strength at high operating temperatu-res. In addition, they must also have enough resistance to corrosion and to scaling at the opera-ting temperature. The high-temperature strength and creep resistance are improved through theaddition of particular alloying elements such as Cr, Mo, V, W, Co, Ti and Nb. In metallurgical terms,this happens through the mixed-crystal formation and the development of finely distributed specialcarbides and nitrites during the quenching and tempering process.

The resistance to corrosion and scaling is adjusted through the Cr content.

For temperature stresses up to 550°C, small additions of Mo, V and Cr are sufficient; Mo has thegreatest effect on increasing the creep resistance. Increased scaling resistance is also requiredabove 550°C. The 9 - 12% Cr steels with added Mo, W, Co, V and Nb may be considered for thesepurposes. The creep strength of quenched and tempered steels drop so significantly above 620°Cthat special Cr-Ni steels (base type: 16% Cr, 13% Ni) or Ni-based materials have to be used. Thecreep resistant steels are standardised in EN 10028-2, EN 10222-2, EN 10213, EN10216-2 andelsewhere.

Welding the creep resistant steelsThe creep resistant steels can be divided into three main groups:

1. Ferritic-pearlitic steels(65GH, P355GH and 16Mo3)

The steels are available in normalised condition. There is no risk of hardening in the zone affected by heat. Above a certain wall thickness, however, preheating to 150°C is required (P265GH = 25 mm; 16Mo3 = 15 mm.)

2. Bainitic (martensitic) ferritic steels(e.g. 13CrMo4-5, 10CrMo9-10, 14MoV6-3).

These steels are available in tempered condition, and are air-hardening, which calls for specialattention when welding. Hard, brittle zones can develop through the formation of martensite in theHAZ of the base material and in the weld metal itself, and this can cause cracking. For this reason,preheating to temperatures between 100 and 300°C, depending on the type of steel, should the-refore be carried out, and the interpass temperature taken into account. Since the preheating andinterpass temperatures lie below the Ms temperature (Ms = 480°C), subsequent tempering isnecessary at temperatures in the range between 640 740°C, depending on the steel type, but inany case below Ac3. Notes on the selection of the preheating and interpass temperatures are givenin Table C5 of BS EN 1011-2.

2.1 Bainitic steels(e.g. 7CrMoVTiB10-10,7CrWVNb9-6 )

These new steel types are preferred for the construction of boiler walls.In this thin-walled range, the steels are welded, with appropriate preheating. Subsequent heat tre-atment is often omitted. Thicker walls are annealed at 740°C after welding.

3. Martensitic steels – alloy basis 12% chromium(e.g. 12% Cr steels X20CrMo12-1, X22CrMoV12-1 and X22CrMoWV12-1).

The steels are available in quenched and tempered condition. The largely martensitic microstruc-ture means that very careful heat control must be exercised during welding. Two different techni-ques have become accepted in practice, and are known as martensitic and austenitic welding.

The difference lies in the preheating and interpass temperatures. For austenitic welding, this isabove the Ms temperature (400 to 450°C), while in the case of martensitic welding, it is below theMs temperature (between 200 and 250°C). After welding, the work is cooled to between 80 and120°C, followed by heat treatment in the temperature range between 720 and 780°C.

A special example of the 12% Cr steels is the new X12CrCoWVNb12-2-2 steel. This steel exhibitsa high resistance to scaling together with good creep strength at temperatures up to about 650°C,and is used for superheater pipes. Preheating temperatures are 150-200°C, interpass temperatu-res are at most 280°C, same-type consumables are used, and subsequent heat treatment is car-ried out at about 770°C.

3.1 Martensitic steels – alloy basis 9% chromium(e.g. X10CrMoVNb9-1, X11CrMoWVNb9-1-1, X10CrWMoVNb9-2) ,

In contrast to the 12% chromium types, the 9% chromium types feature, in particular because ofthe lower C content, a reduced tendency to harden during welding, as a result of which the risks ofcold cracking and the occurrence of stress corrosion cracking are reduced. Preheating and inter-pass temperatures in the range between 200 and 300°C should nevertheless be provided.

Because the welding technique has a significant effect on the achievable toughness of the weldmetal, the use of multi-pass techniques, i.e. lower layer thicknesses, is recommended. This creates a high proportion of quenched and tempered microstructure in the weld metal, and thusimproves the toughness.

Prior to the necessary tempering (740 - 760°C), intermediate cooling to room temperature is neces-sary, in order to achieve complete martensite conversion.

Selecting welding consumablesSame-type alloyed welding consumables are normally used. It is only if this precondition is fulfilledthat the welded joint can be expected to have a creep strength that matches the base material.Stick electrodes include those with a basic or rutile coating. Due to their poorer mechanical pro-perties and their higher hydrogen content, the latter are only used for steels up to at most 1% Crand wall thickness up to 12 mm. Rutile coated stick electrodes are mostly used for root welding.

TIG welding is often used for the root pass on pipes. Gas shielded metal arc welding with solid elec-trodes, and also particularly with flux cored wires are also becoming increasingly important, as isthe SAW technique.

Selection guide

High pressure hydrogen resistant steelsSteels with little tendency to decarburisation by hydrogen at high pressures and temperatures, andto the embrittlement and grain boundary cracking that are associated with it, are classified as highpressure hydrogen resistant. These properties are achieved by alloying with elements that formhighly stable carbides that are difficult to decompose at the operating temperature. Chromium isone such element. High pressure hydrogen resistant steels include, for example, 25CrMo4,20CrMo9, 17CrMoV10, X20CrMoV12-1, X8CrNiMoVNb16-13 according to the steel-iron materials data sheet 590.

Hydrogen penetrates the steel at high pressure, and reacts with the carbon in the iron carbide orpearlite, forming methane. Because the methane molecules, due to their size, do not defuse veryeasily, high pressures develop inside the steel, and these can result in breakup of the microstruc-ture and finally to intercrystalline cracks.

Welding high pressure hydrogen resistant steelsIf the necessary precautionary measures are taken, high pressure hydrogen resistant steels aresuitable for welding. Increasing the carbon content, however, impairs the suitability for welding.Prior to welding, these steels should be preheated to between 200 and 400°C, depending on thesteel type, and this temperature must be maintained when welding.

After welding, cooling must be slow and even. The subsequent heat treatment must be carried outaccording to specifications. The welding consumables must also yield a weld metal that is highpressure hydrogen resistant. The X20CrMoV12-1 and X8CrNiMoVNb16-13 steels require a veryspecial welding technique.

3.4.7. Stainless steels


The stainless steels group contains a large number of very different kinds of alloy, whose commonfeature is a chromium content of at least 12%. This ensures that, under oxidising conditions, anextremely thin, stable, layer of oxide forms on the surface of the steel, and the steel changes froman active (soluble) into a passive (insoluble) condition. The resistance to oxidising media is increa-sed in the passive condition. In the presence of a reducing environment, however, i.e. when thereis little available oxygen, the otherwise passive steel changes into the active condition. The chro-mium content of at least 12% that is required for a degree of chemical resistance of the steel, isvery often referred to as the "parting limit". The alloying element chromium, and, following on fromthat, nickel, are the basic elements for stainless steels. The effect that they have on the micro-structure within the steel is, however, very different.

Whereas the gamma region is protected as the chromium content rises and, with 12% or more, onlyferrite (body-centred cubic solid solution) is the predominant form between the solidification androom temperature, rising nickel content expands the gamma region. Above a certain nickel content,the microstructure only comprises austenite (face centred cubic solid solution) between the solidi-fication temperature and room temperature.

The effect on the formation of the microstructure of all the other alloying elements that are addedto steel in order to improve particular properties can be classified as either chromium-like or nickel-like. This means that it is possible to distinguish between ferrite-forming and austenite-forming ele-ments, as follows.

Ferrite-forming elements: chromium, silicon, aluminium, molybdenum, niobium, titanium, tungstenand vanadium.Austenite-forming elements: nickel, manganese, carbon, cobalt, copper and nitrogen.

If sufficient quantities of nickel are added to a ferritic iron-chromium alloy, it converts to the aus-tenitic state.

The important groups of stainless steels are listed in the following table. They are divided accor-ding to the microstructure.

Microstructure Material typesPearlitic-martensitic X30Cr13Semi-ferritic-ferritic X8Cr17Soft martensitic X5CrNi13-4Ferritic-austenitic X2CrNiMoN22-5Austenitic Austenite with ferrite X5CrNi18-9

Austenite without ferrite X8CrNiNb16-13

These steel groups differ both from the metallurgical and the physical point of view, and suitablemeasures must be taken when welding to allow for their special features.


A few characteristic martensitic Cr steels and their suitability for welding:

Material designation %C %Cr %Mo Welding suitabilityX12Cr13 0.15 13.0 - limitedX20Cr13 0.20 13.0 - very limitedX39CrMo17-1 0.42 16.5 1.2 none

Basically this group of steels must be considered as having only limited suitability for welding. Asthe carbon content rises, the risk of cold cracking increases, and joint welding should be avoidedas far as possible.

The most important alloying element is chromium which, when the content is about 12%, lends itspassivity, and therefore its corrosion resistance in oxidising media, to the steels. As a ferrite-formingelement, chromium restricts the austenite region of the iron; with about 13% chromium it is entire-ly choked off. Steels with chromium contents of greater than 13% and with very low carbon con-tents (< 0.1%) do not undergo any conversion as they cool from the solidification temperature toroom temperature. These are the ferritic Cr steels.

The group of hardenable steels begins at chromium contents above 12% and carbon contents ofabout 0.1 to 1.2%. These are the martensitic chromium steels. As a result of the higher-carbon con-tent, the austenite region is extended, and this creates the possibility of hardening.

Welding martensitic chromium steelsThe austenitic component in the heat affected zone of the base material is always converted tomartensite with air cooling, since the formation of pearlite and intermediate phases is heavily delay-ed by the high chromium content.

Due to the high chromium content of the steel, the conversion to pearlite, in which the delta-ferriteand the carbide are precipitated from the gamma solid solutions, only begins after a very long time.As a result, the weld metal, and the heat affected zone (HAZ), effectively always convert to the mar-tensitic phase, unless it is heated above the martensite conversion temperature.

If we consider the increasing hardness of this kind of steel in relation to the carbon content, theirunfavourable or inadequate suitability for welding can easily be understood.

Increase in hardness for various carbon contents:

Carbon content Hardness0.10% C ca. 40 HRC0.15% C ca. 46 HRC0.20% C ca. 50 HRC0.25% C ca. 53 HRC0.40% C ca. 56 HRC0.70% C ca. 58 HRC1.00% C ca. 60 HRC

At the same time we can also understand that, in practice, martensitic Cr steels with less than0.15% carbon are almost the only ones used for welded constructions.

The role played by hydrogen during welding represents a further disadvantageous factor.Particularly when brittle martensite is present, higher hydrogen contents can lead to a strong ten-dency to hydrogen-induced cold cracking in the welded joint.

Because the martensite is relatively hard, brittle and at the same time sucseptable to corrosion, the13% Cr steels are always quenched and tempered, while 17% Cr steels are quenched and tem-pered or soft annealed.

This group of steels is welded using both same type and dissimilar welding consumables.See further below for recommendations about the appropriate welding technology and welding con-sumables. When same type or similar type welding consumables are used, the weld metal, in thewelded condition, consists of martensite and delta-ferrite, with a small proportion of residual aus-tenite. For this reason the figures for elongation and impact energy are very low, and annealing isalmost always done at between 700 and 750°C.

Welding technology

for steels with carbon contents below 0.15%◆ Covered electrodes and SAW flux are to be redried according to the manufacturer's

specifications.

◆ Same type welding consumables should only be used when there is a requirement for colour matching, comparable strength or fatigue strength. Otherwise use austenitic welding consumables.

◆ A preheating and interpass temperature of 200 - 300°C is strictly recommended.

◆ After welding, tempering at 700 - 750°C is to be carried out.Pay attention when using austenitic welding consumables – there is a risk of embrittlement.

The following table contains the chemical composition and the suitability for welding of a numberof ferritic Cr steels characterised by a low carbon content. As a result, these steels are predomi-nantly ferritic from the beginning of solidification down to room temperature. They therefore do notundergo any conversion, and for that reason can also not be hardened.In some cases Mo, Ti or Nb are added to the alloy in order to improve the chemical properties.

Material designation % C % Cr % Mo Welding suitability

A fine-grained structure is a precondition for adequate technical parameters, particularly whereelongation is concerned. This is achieved if the last conversion stages are carried out below 800°C,with subsequent heat treatment up to 800°C followed by fast cooling in air or water. This group ofmaterials is very sensitive to overheating. If exposed to temperatures above 1000°C, the grainstend to become coarser and this, in combination with carbide precipitation, can result in heavyembrittlement. Ferritic Cr steels are therefore also not used for the construction of pressure ves-sels.

In addition, the ferritic Cr or Cr-Mo steels tend, as the Cr content rises, to exhibit a time-dependenthardening phenomenon in the temperature range between 400 and 525°C. This is known as 475°Cembrittlement. It involves a separation of the ferrite into a high-chromium and a high-iron phase.

Welding ferritic Cr steelsParticularly in the case of steels with a high Cr content, the heat introduced during welding causesgrain growth in the highly heated part of the transition zone, and this cannot be rectified by subse-quent heat treatment. In addition, carbide is precipitated at the grain boundaries, leading to a furt-her reduction of toughness. For these reasons, the ferritic Cr steels are classified as having only"limited suitability for welding". Similarly unfavourable conditions are to be expected in the weldmetal when same type welding consumables are used.

The loss of toughness constitutes an absolute weakening of the welded joint. The use of austeni-tic welding consumables is therefore recommended for welding ferritic Cr steels.

Due to its altogether greater toughness, the austenitic weld metal is able to act to some extent asan expansion element. The austenitic weld metal also offers advantages from the point of view ofcorrosion chemistry. There is a disadvantage in the form of the different colouring of the base mate-rial and the weld metal. If colour matching is a necessity, same type alloy welding consumablesmust be used. If gases containing high amounts of sulphur or carburising gases will be present inpractice, it is possible that the austenitic weld metal will be attacked preferentially (e.g. through theformation of nickel sulphide). In this case, the procedure is to fill the joint with austenitic metal, andto weld only the last layers of the medium exposed surfaces using ferritic welding consumables.Welding is carried out after preheating to between 200 and 300°C, in order to keep thermal stres-ses as low as possible. Care is to be taken to introduce as little heat as possible, in order to mini-mise the formation of coarse grains. Annealing in the range from 700 to 750°C is advantageousafter welding. This causes the precipitated carbides to coagulate, whilst reducing tensions at thesame time. Up to a point, both of these factors bring an improvement in toughness.

The coarse grains in the heat affected zone can not, however, be overcome. When austenitic wel-ding consumables are used, it is necessary to allow for their tendency to precipitate intermetallicphases (embrittlement) in the temperature range between 600 and 900°C.

Steels with a soft martensitic microstructure have a wide range of applications. The steel type with12% chromium and 4% nickel is the most important representative of this group of steels.Information on chemical composition and suitability for welding is contained in the following table.

Material types % C % Cr % Mo % Ni Welding suitability

X5CrNi13-1 <0.05 13.0 0-0.4 1-2.0 goodX5CrNi13-4 <0.05 13.0 0.4 4.0 goodX5CrNi13-6 <0.05 13.0 0.4 6.0 goodX5CrNi16-6 <0.05 16.0 - 6.0 good/limitedX5CrNiMo16-5-1 <0.05 16.0 1.5 5.0 good/limitedX5CrNi17-4 <0.05 17.0 - 4.0 good/limited

This kind of material exhibits a very wide range of mechanical properties, depending on its chemi-cal composition and, above all, on the type of heat treatment. For this reason, only the X5CrNi13-4 type will be considered closely in what follows.

The basic ideas behind the development were, firstly, to lower the carbon content in order to increa-se the toughness of the martensitic structure and to reduce the tendency to cold cracking, whilstachieving a microstructure as free as possible from delta-ferrite by alloying with between 4 and 6%nickel.

At "room temperature" the microstructure thus consists of "soft" martensite with small quantities ofsupercooled delta-ferrite and austenite. Tempering further increases the toughness and lowers thehardness or strength. At the same time, the low carbon content and the inclusion of about 0.5%molybdenum in the alloy increase the corrosion resistance.

A significant advantage of the soft martensitic chromium-nickel steels lies in their good suitabilityfor welding when compared with plain chromium steels.

The suitability of the soft martensitic steels for welding is largely characterised by three properties,namely:

1. The formation of low-carbon, tough martensite in the HAZ and in the weld metal, so greatly reducing the tendency to cold cracking.

2. A low delta-ferrite content. To a large extent this counters the tendency to form coarse grains when welding.

3. The sensitivity of the martensitic microstructure to hydrogen. Hydrogen-induced cold cracking can occur if the content of diffusible hydrogen is > 5 ml / 100 g.

Welding soft martensitic Cr-Ni steelsThe type of heat treatment applied has an important effect on the mechanical properties of thesematerials. Soft martensite with a nickel content of more than 3.5% exhibits a special metallurgicalbehaviour, namely the formation of finely dispersed austenite at tempering temperatures above580°C. This effect results in an increase of the values for impact energy in the 13/4 weld metal. Thehighest values are achieved through tempering at between 600 and 620°C. At higher temperingtemperatures, the impact energy falls again due to the conversion of the tempered austenite intomartensite as it cools.

The selection of the interpass temperature is of special importance if cold cracking is to be avoidedin the welded joint. Practical experience of soft martensitic materials indicates that a sudden "flip-ping" of large regions of the welded seam into martensite should be avoided when cooling afterwelding. Otherwise, extremely high conversion stress and internal stress conditions must be expec-ted in the weld metal, and these can later result in cold cracking. Interpass temperatures that lieclose to the Ms temperature must therefore be considered critical.

It is recommended that the interpass temperature should be kept in the range between 120 and220°C for the X5CrNi13-1 weld metal, and between 100 and 160°C for the X5CrNi13-4 andX5CrNi13-6 weld metals.

As a result, a martensite conversion of about 50% occurs in the weld bead, which is advantageousfrom the metallurgical point of view and from the point of view of stress. Accurately maintaining thequoted interpass temperature is of particular importance when it is not possible to carry out a sub-sequent heat treatment.

Welding technologyIn the light of the special features of welding soft martensitic steels, it is recommended that the wel-ding technique described below is followed. These notes apply to the most important soft marten-sitic steel, containing 13% Cr and 4% Ni.

◆ Only same type alloy welding consumables should be used for joining.

◆ Covered electrodes and SAW flux are to be redried in accordance with the manufacturer's specifications in order to maintain a hydrogen content of < 5 ml/100 g in the weld metal.

◆ Thick walled components should be preheated to 100°C, and welded using an interpass temperature in the range between 100 and 160°C.

◆ Tempering, or quenching and tempering is required after welding in order to increase toughness.


The group of austenitic chromium-nickel-(molybdenum) steels is the most significant of these stain-less materials. Generally speaking, these chemically resistant steels can be classified as "very wellsuited to welding". They cannot be quench hardened, which means that hardening does not occurin the heat affected zone, and there is no significant grain coarsening. Nevertheless, unsuitablehandling can, in some circumstances, cause three problems, both in the base material and in theweld metal. These are:◆ Sensitisation, i.e. a reduction in the resistance to corrosion due to the formation of

chromium carbide.

◆ Hot cracking, i.e. separation of grain boundaries during solidification, or in the highly heated HAZ when rigidly fixed.

◆ Embrittlement, i.e. the precipitation of intermetallic phases such as the sigma phase through exposure to high temperatures or annealing.

When welding the fully austenitic steels, their inherent tendency to hot cracking must also be con-sidered.

Notes on the welding techniques for standard austenitic Cr-Ni-(Mo) steels, the subsequent heat tre-atment of the weld seams, and information on welding consumables can be found in the corre-sponding sections.

Welding technology

◆ Only grades corresponding to the base material concerned should be used for welding. The delta-ferrite content of the weld metal should be in the range between 3 - 15 FN (ferrite number).This ensures sufficient resistance to hot cracking. For highly corrosion-resistant special steels,same type welding consumables that yield a fully austenitic weld metal are also available.

◆ Ensure that austenitic steels are only processed when their surface is clean and dry.◆ The arc should be kept as short as possible in order to avoid picking up nitrogen from the air.

When welding with shielding gas, it is necessary to make sure that the gas shield is working perfectly. With the exception of flux cored wire welding, only shielding gases with a low CO2content should be used in order to keep carburising of the weld metal to the lowest possible level.

◆ Preheating to 100 - 150°C is only advisable if the base material is thick, but it is not necessary in principle.

◆ An interpass temperature of 150°C should not be exceeded.◆ Ensure that the current intensity is kept within the recommended range.◆ If it is not possible to reweld the root when welding with shielding gas then shielding gas

(e.g. forming gas or pure argon) must be applied from the rear when welding the root.◆ If possible, dilution with the base material should be kept below 35%. If, as a result of the

welding method, it is higher than this, the ferrite content of a test seam must be determined with a calibrated ferrite content meter or an estimate must be calculated from the chemical composition, e.g. using the WRC-92 diagram. The ferrite content, i.e. the FN, should not be below the minimum figure mentioned above.

◆ Annealing treatment after welding should be avoided at all costs. If this is not possible, then it must be expected that the corrosion resistance and/or toughness may be impaired. In such cases consultation with the manufacturer of the steel and of the welding consumable is recommended.

◆ In general it is possible to use unstabilised, low-carbon welding consumables for stabilised steels and vice versa, but the limit temperature for intergranular corrosion must be borne in mind.

◆ Greater distortion than when welding ferritic steels must be allowed for, and corresponding countermeasures, such as the seam shape, stronger tacking, pre-stressing, back-welding and so forth must be considered.

◆ Straightening with the gas flame should not be done if at all possible, as corrosion resistance can suffer from this. The harmful effect of arc strikes outside the welded joints should also be particularly stressed in this context.

◆ Only slag hammers and brushes of stainless Cr or Cr-Ni steels should be used for cleaning austenitic welded joints.

Subsequent treatment of welded seamsIt must be stressed that an entirely clean metal surface is a precondition for optimum corrosion resi-stance. It is not only necessary to remove all the welding scales, the slag and spatter, but all theannealing colours must also be eliminated.

Subsequent treatment can comprise grinding, pickling, blasting with quartz, corundum or glassbeads, brushing and/or polishing. The finer the surface, the better is the corrosion resistance (e.g.rough grinding – fine grinding – polishing).

Pickling is used most often. A variety of pickling solutions or pastes are available for this purpose.They are applied to the surface, and after the recommended exposure time must be thoroughly rin-sed with water.

Removing the "annealing colours" from welded seams can be a problem. These too can be remo-ved by washing with quartz sand or by brushing.

If the pickled component will soon be exposed to corrosive agents, as is frequently true for repairjobs, then passivation is recommended after the pickling. Thorough rinsing is again necessary afterthe passivation treatment.

While we are talking about the application of pickling agents, it is important to stress that these arehighly caustic substances. It is therefore essential that protective gear such as rubber gloves, rub-ber aprons, eye protection and possibly breathing protection are used. Local environmental pro-tection regulations must also be observed.

Blasting with quartz, corundum or glass beads is used when grinding or pickling are ruled out. Thismethod must only be applied using the said materials. The method does yield a clean, metallic sur-face, but one that is somewhat rough.Passivation should also be carried out after blasting.

The austenitic, chemically resistant Cr-Ni steels are generally well-suited to welding. Nevertheless, thespecial physical properties of these steels – low thermal conductivity and high coefficient of thermalexpansion – must be considered when welding, as they are relevant to heat control. The type of pri-mary solidification is particularly important to these materials, and later has a significant effect on thehot cracking behaviour.For the welding practitioner, the presence of a certain proportion of ferrite in the weld metal is an indi-rect indication of adequate resistance to hot cracking. Ferrite in the weld metal is generally favoura-ble for welded seams that are not able to expand freely, when the cross-section of the weld seam islarge, and when cracks have already impaired the suitability for use. Ferrite increases the strength ofthe weld metal, but has a disadvantageous effect on the resistance to corrosion in certain media. It isalso unhelpful for low-temperature applications, and in the high temperature range where conversionto the brittle sigma phase is possible.In addition to metallurgical estimation, the ferrite content can be determined magnetically or throughcalculation. The scale used is not absolute, which means that it can be expected that measurementsfrom different laboratories give different results (e.g. results scattered between 3.5 and 8.0% for asample with about 5% of delta-ferrite). The measurements are usually reported in FN (ferrite num-bers). Up to about 10 FN the ferrite number can be equated to the percentage of ferrite.It is the opinion of the Welding Research Council (WRC) that it is not at present possible to determinethe absolute ferrite content of austenitic-ferritic weld metals. Scatter can also be expected from sam-ples with pure weld metal, resulting from variations in the welding and measurement conditions. Theusual standardisation assumes a 2 sigma scattering, which implies a variation of ± 2.2 FN for an FN 8.Greater scatter can be expected if the welding technique permits a high uptake of nitrogen from thesurrounding air. A high nitrogen pickup can have the result that a weld metal with 8 FN can fall to 0 FN. A nitrogen pickup of 0.10% typically lowers the ferrite content by 8 FN. Dilution with the basematerial results in weld metals whose ferrite content has been lowered further, since the same typebase materials usually have lower ferrite contents than the pure weld metal.As an alternative to measurement, the ferrite content can also be calculated from the chemical com-position of the pure weld metal. A variety of microstructure diagrams can be employed for this purpo-se. These include the WRC-92 diagram, the Schaeffler diagram, the DeLong diagram and the Espydiagram. The results obtained from the individual diagrams can vary strongly, since they have beenprepared on the basis of series investigations for a variety of materials groups.The WRC-92 diagram provides a prediction of the ferrite content, expressed in FN. It is the mostrecent of the listed diagrams, and has shown better agreement between the measured and estimatedferrite contents than when the DeLong diagram is used. It should be noted that the WRC-92 diagramdoes not consider the silicon or manganese content, which means that its applicability to high-siliconand high-manganese (more than 8%) weld metals is limited. In addition, if the nitrogen content is morethan 0.2%, it is again of limited applicability.The Schaeffler diagram is the oldest of the listed diagrams, and in the past has been widely used forthe calculation of ferrite content. It can be applied over a wide range, but does not take account of thestrong austenitising effect of nitrogen.The Espy diagram attempts to compensate for these weaknesses. Like the Schaeffler diagram, it cal-culates the ferrite content in percent, but does handle manganese contents of up to 15% and nitrogencontents of up to about 0.35%.The DeLong diagram is a modification of the Schaeffler diagram, expressing the ferrite content in fer-rite numbers up to about 18 FN. The diagram does take the nitrogen content into account, and provi-des better agreement between measurement and calculation than the Schaeffler diagram. Its appli-cable range is quite similar to that of the WRC-92 diagram.

If the nitrogen content is not known for determining the nickel equivalent, then a content of 0.06%can be assumed for TIG welding and for manual electrode welding, or 0.08% for gas shielded arcwelding with solid wire electrodes. The ferrite number can be predicted using the WRC-92 diagram– assuming that the chemical composition is correct – over a range of ± 3 FN in about 90% of mea-surements.

The effect of delta-ferriteThe following summary covers the advantages and disadvantages of delta-ferrite in an austeniticweld metal. Basically, the comments also apply to the steel material.

Depending on the conditions of practical use, delta-ferrite may sometimes be unwanted, but isadvantageous in the majority of cases and sometimes even required. The reasons for what at firstmay appear to be conflicting requirements are provided in the summary. The consequences ofdeviating from it are also indicated.

Steels that feature particular resistance to scaling caused by gases at temperatures above around600°C are classified as heat-resistant. A steel is classed as heat-resistant if, at a temperature x, theweight of the metal that turns to scale at this temperature does not, on average, exceed 1 g/m2*h, and does not exceed 2 g/m2*h at a temperature of (x + 50°C), when stressed for 120 hours with four intermediate coolings.

Information and notes on the resistance to scaling and/or to the highest application temperaturesis contained in, for example, SEW 470, but this must only be used as a guide. Under unfavourableconditions, e.g. in sulphurous or reducing gases, particularly when the water vapour content is highor when there is a possibility that aggressive dust may be deposited, the range of temperatures forapplication is lower. On top of this, the possibility of sigma phase precipitation must be considered.

The important groups of heat-resistant steels are listed in the following table. They are dividedaccording to the microstructure.

Microstructure Typical examplesFerritic X10CrAlSi7, X10CrAlSi13, X10CrAlSi25Ferritic-austenitic X20CrNiSi25-4Austenitic X12CrNiTi18-9, X15CrNiSi25-21, X12NiCrSi36-16

Welding heat resistant steelsDepending on the conditions of the practical application, ferritic chromium steels may be joinedusing same type alloys, or, predominantly, using austenitic welding consumables. Preheating andinterpass temperatures in the range between 200 and 300°C are recommended for thicker crosssections. Subsequently, the toughness properties impaired by the formation of coarse grains andby carbide precipitation can be improved through a heat treatment at between 700 and 750°C.

The steels with a ferritic-austenitic microstructure are usually welded using same type welding con-sumables, without preheating or subsequent heat treatment.

With fully austenitic chromium-nickel steels and welding consumables, their inherent tendency tohot cracking must be borne in mind. In the temperature range between 600 and 900°C, the possi-bility of embrittlement through the precipitation of intermetallic phases must be considered.

Both same type alloy welding consumables and nickel-based welding consumables are sometimesused.

3.4.13. Heat-resistant steels


The number of possible dissimilar joints between the very different kinds of steel is so enormousthat it is practically impossible to record every single combination of materials. For this reason,there are only a few associated standards or sets of regulations.

Basic general rules in the form of notes, recommendations and precautionary measures for the sel-ection of welding consumables and the development of suitable welding techniques are thereforelisted below. These basic rules, however, are only helpful if their practical implementation is donewith enough technical expertise and enough fundamental metallurgical knowledge.

When joining different materials, there are many cases in which it is not possible to select the opti-mum welding consumable and welding conditions for both individual materials. Suitable compro-mises must therefore be found.

The selection of the suitable welding consumable is an important criterion for welding dissimilarjoints. The consumable must be chosen in such a way that no excessively hard, brittle or easilycracked weld metal is created when it becomes diluted with the different base materials.General notes and recommendations for the selection of welding consumables for dissimilar jointsare given below. It must be borne in mind here that a large number of different factors are relevantto the selection of suitable welding consumables, and not all of these can be covered in this chap-ter. For this reason, the manufacturer and designer should be consulted over the selection of wel-ding consumables.

Unalloyed – unalloyed(e.g. S235JR with S355J2)

Unalloyed types of steel with different strengths are often joined together in practice. The mecha-nical properties of the base materials are the main things to be considered in the case of suchjoints. As a rule, welding consumables whose strength corresponds to the softer base material areused. It must, however, be noted that, due to the fine-grained structure, unalloyed weld metalsrarely fall below 0.2-offset yield strengths of 400 MPa.

The choice between coating, filling and flux types is made in the light of the welding method, bea-ring in mind the wall thickness and the component stiffness. At higher strengths, or when a com-ponent will be subjected to stress, the use of basic welding consumables or auxiliary materials isto be recommended. Their metallurgically pure weld metal, associated with low hydrogen contents,ensures good resistance to cracking

Unalloyed – creep resistant(e.g. P235GH with 13CrMo4-5)

For these joints a welding consumable of a similar type to the lower-alloy material is used as a rule.If subsequent heat treatment is required, the annealing temperature must be appropriate for thetwo base materials and for the welding consumable.

Unalloyed – high-strength(e.g. S235JR with S460N)

The welding consumables are usually matched to the softer base material.

If the strengths of the two materials are very different (e.g. S235JR with S690Q), the welding con-sumables should have strengths between the values for the two base materials. Welding techniqueshould be matched to the higher-strength base material.

3.4.14. Welding dissimilar joints

3-72

Selection guide


3-73


Unalloyed – cryogenic(e.g. S235JR with 15NiMn6)

With low-temperature steels containing up to 3.5% Ni, unalloyed welding consumables can beused, as well as welding consumables of the same or similar alloy to the material that contains Ni.If the Ni content is between 5 and 9%, austenitic or nickel-based welding consumables should beused.

Unalloyed – quenched and tempered steels(e.g. S235JR with 42CrMo4)

Quenched and tempered steels only offer limited suitability for welding. The steels must be prehea-ted, and must be subjected to subsequent heat treatment.

Either unalloyed or alloyed welding consumables may be considered, depending on the pair ofbase materials. Dilution should be kept to a low level. In special cases, nickel-based welding con-sumables may also be used.

In exceptional cases in which subsequent heat treatment is not possible, the use of over-alloyedaustenitic Cr-Ni welding consumables (e.g. BÖHLER A 7 CN-IG) may be advantageous.

Unalloyed – chrome steels(e.g. S235JR with X12Cr13)

Both ferritic and martensitic Cr steels require special heat control when welding, and subsequentannealing. For this reason, the use of nickel-based alloys (depending on the conditions of use) isto be recommended.

If subsequent annealing is not possible, and if the operating temperature is limited to a maximumof 400°C, then austenitic over-alloyed welding consumables may also be used.

Unalloyed – austenite(e.g. S235JR with X5CrNi18-10)

A complex metallurgical problem is presented when steels with very different chemical compositi-ons are to be joined, and it can only be solved through compromise. In general, over-alloyed aus-tenitic welding consumables are to be used.

The selection of the welding consumable is of crucial importance for this type of dissimilar joint.Bearing in mind the dilution with the different base materials, a weld metal having neither a mar-tensitic microstructure, nor an austenitic-ferritic microstructure containing 0 to 5% δ-ferrite shouldbe formed. In this way a crack-free, tough welded joint between the unalloyed steel and the aus-tenitic material is ensured. The dilution between the base materials and the welding consumableshould here be kept as low as possible. The Schäffler diagram can help to select the welding con-sumables.

If the welding is to be carried out under circumstances that are subject to acceptance tests, anickel-based consumable material should be used if subsequent heat treatment is carried out, if theoperating temperature is above 300°C, or if the walls that are to be welded are thicker than 30 mm.

High-strength – high-strength(e.g. S460N with S890Q)

For dissimilar joints of high-strength fine-grained structural steels, the selection of the strength ofthe welding consumable should be oriented around the softer steel type.

If the strength characteristics of the two materials are very different (e.g. S460N with S890Q), awelding consumable with a strength between that of the base materials is to be used. Otherwise aweak point will be created in the component as a result of the large step in strength in the regionof the welded joint. Welding technique should be matched to the higher-strength base material.


High-strength – austenite(e.g. S460N with X5CrNi18-10)

As is the case of joints between unalloyed steel and austenite, over-alloyed austenitic welding con-sumables are to be used.

If the welding is to be carried out under circumstances that are subject to acceptance tests, anickel-based consumable material should be used if subsequent heat treatment is carried out, if theoperating temperature is above 300°C, or if the walls that are to be welded are thicker than 30 mm.

Cryogenic – cryogenic(e.g. S275NL with 15NiMn6)

The welding consumables are to be selected bearing in mind the necessary low-temperature toug-hness. For dissimilar joints on steels with up to 3.5% Ni, a welding consumable that matches oneof the two materials is adequate.

If the Ni content is between 5 and 9%, austenitic or nickel-based welding consumables should beused.

Cryogenic – austenite(e.g. 15NiMn6 with X5CrNi18-10)

The welding consumables are to be selected bearing in mind the necessary low-temperature toug-hness. Over-alloyed fully austenitic welding consumables should mainly be considered.

Creep resistant – creep resistant(e.g. 16Mo3 with 13CrMo4-5)

For these joints a welding consumable of a similar type to the lower-alloy material is used as a rule.

The subsequent heat treatment must be appropriate for both the base materials and for the wel-ding consumable. For the construction of steam boilers, the associations have provided, inAgreement 2003/3 (Steam Boilers), binding rules for the selection of welding consumables andannealing temperatures.

Creep resistant – austenite(e.g. 13CrMo4-5 with X5CrNi18-10)

Nickel-based welding consumables are mostly used for these joints, since the majority of creep-resistant steels need to be strongly preheated and subjected to heat treatment. Since many aus-tenitic steels tend to exhibit σ-phase embrittlement at temperatures above 400°C, the weld edgesof the creep resistant material should be plated with 3 layers using a nickel-based welding consu-mable, and then annealed. Only then should the joint be welded. Only in exceptional cases canover-alloyed austenitic welding consumables also be used.

Quenched and tempered steels – quenched and tempered steels(e.g. 25CrMo4 with 42CrMo4)

Quenched and tempered steels only offer limited suitability for welding. Their suitability for weldingfalls as the C content rises. They require special heat control while welding, as well as subsequentannealing. Same-type welding consumables scarcely exist. The selection is made in accordancewith the given strength, bearing in mind the necessary heat treatment. In many cases the conditi-ons of practical application permit the use of softer welding consumables. Nickel-based weldingconsumables can also be used.

Only in those cases where no subsequent heat treatment will be carried out should the use of over-alloyed austenitic Cr-Ni welding consumables be considered.

Quenched and tempered steels – austenite(e.g. 42CrMo4 with X5CrNi18-10)

The restricted suitability for welding, as well as the necessary subsequent heat treatment, meanthat nickel-based welding consumables must be used, that the welding edges of the quenched andtempered steel are plated with 3 layers, and that annealing is carried out afterwards.

Only when no heat treatment is carried out can over-alloyed austenitic welding consumables beused; in this case an operating temperature of at most 400°C should not be exceeded.

Austenite – austenite(e.g. X5CrNi18-10 with X6CrNiMoTi17-12-2)

The welding consumable should be selected to match the chemical composition of the higher-alloymaterial.

Austenite – chrome steels(e.g. X5CrNi18-10 with X12Cr13)

The selection of the welding consumable depends on the operating conditions.

Both ferritic and martensitic Cr steels have only limited suitability for welding. For this reason, spe-cial heat control during welding and subsequent heat treatment are required.

It is therefore necessary to take account of the tendency to embrittlement when specifying aus-tenitic welding consumables. In some cases this can require the use of nickel-based welding con-sumables.

Austenite – heat-resistant(e.g. X5CrNi18-10 with X8CrNi25-21)

Welding consumables whose alloy corresponds to that of the heat-resistant material, should main-ly be used.

Nickel-based – nickel-based(e.g. Alloy C 625 with Alloy C 22)

The choice of welding consumable must be considered separately for every pair of materials.

Nickel-based – unalloyed / creep resistant / high-strength / cryogenic / quenched and tempered steel

(e.g. C 276 with S235JRG1 /13CrMo4-5 /S460N /14Ni6 /24CrMo4)A range of differently alloyed nickel-based welding consumables is available for these kinds of dis-similar joints. In many cases a welding consumable with the same type or similar type alloy to thenickel-based base material is used.

Nickel-based – chromium steel / austenite / heat-resistant(e.g. C 276 with X12Cr13 / X5CrNi18-10 / X8CrNi25-21)

The conditions in which the weld will be used must be considered when choosing the welding con-sumable. Usually a welding consumable with an alloy of the same or similar type as the nickel-based alloy is used.

Hard manganese steel – unalloyed(e.g. X120Mn12 with S235JRG1)

The use of austenitic Cr-Ni welding consumables with an increased Mn content, or over alloyedtypes, is recommended.

Hard manganese steel – austenite(e.g. X120Mn12 with X5CrNi18-10)

Austenitic types with an increased Mn content, or over alloyed types, are recommended as the wel-ding consumable.

OverviewA correct welding technique is an important precondition for the fabrication ofwelded joints that meet their requirements. This section will not go into everyfacet of the question, but a number of points will be selected that are oftenthe subject of enquiries from welding engineers.

Steel hardening during weldingDue to the fact that, during welding, certain regions of the base material in the heat affected zonewill always be heated above Ac1 or Ac3, there is a risk that hardenable steels will harden and the-refore develop cracks. The tendency of unalloyed and alloyed steels to harden depends in parti-cular on the carbon content, but also on the alloy contents. During welding, the rate of cooling outof the austenite region can be so great that it corresponds very much to hardening in water.

The rate of cooling is greater when

◆ less heat is introduced during welding,

◆ the material is thicker,

◆ the material is colder.

If the critical rate of cooling is reached, the formation of martensite must be expected. The magni-tude of the hardness figure depends largely on the carbon content.

The hardness rises linearly as the carbon content rises up to about 0.45% C, reaching a value ofaround 650 HV. The impact energy in a hardened steel with up to 0.12% carbon is more than 78 joules, and drops off steeply at higher C-contents. Above 0.2% C it is less than 32 joules. It canbe seen from this that the value of 0.2% C is approximately the limit up to which steels can be wel-ded without preheating and without taking special precautions.

If the filler and cover passes are welded on top of the root pass, the zones underneath are norma-lised or tempered, and the peaks of hardness close to the root seam are reduced. However, ifcracks have already formed in the transition zone due to the hardening that follows the welding ofthe root pass, these remain even after the further passes are applied to the welded joint, and insome circumstances can cause the welded component to fracture.

In zones that have been hardened in this way, welding shrinkage leads to high stresses, since thematerial is prevented from dispersing it through plastic deformation. In addition, particularly whenthe cross sections are thick, multi-axis stress develops in this region, further encouraged by the factthat the formation of martensite is accompanied by an increase in volume. If the stresses reach thecohesion strength, cracks will occur in the transition region.

Hydrogen can play a large part in the creation of these underbead cracks. In order to have somecertainty of avoiding underbead cracks, a hardness value of 350 HV should not be exceeded if atall possible.

In order to avoid underbead cracks, and therefore to guarantee the safety of a welded construc-tion, an accurate knowledge of the hardening processes in the heat affected zone of the steel is,for the reasons mentioned above, of great importance. It also appears very important that, with agiven steel having a known chemical composition prior to welding, predictions can be made aboutthe possibility of hardening.

Preheating the materialThe preheating temperature is the temperature to which the workpiece must be brought in the regi-on of the welded joint before welding the first bead.

3.5.1. Instructions for preheating materials

Selection guide


3-79

Reasons for preheatingThe heat introduced into the workpiece during welding, and thus the steepest temperature gradi-ent that occurs in the zone between the weld metal and the unaffected base material, can result inchanges in the material (risk of cracking). Preheating reduces the temperature gradient, and ensu-res slow cooling. This means that the critical cooling rate, which can lead to disadvantageous chan-ges in the microstructure, is not reached (hardening is slight or non-existent – no risk of cracking).In addition, the shallower temperature gradient reduces shrinkage, and fewer distortions thereforeoccur. The internal stresses caused by welding are reduced, and at the higher temperatures thehydrogen has more time to diffuse out (lower hydrogen content – lower risk of hydrogen-inducedcracking).

A steel must always be preheated before welding if there is a risk of critical changes in the micro-structure. This applies in particular to tack welding. The necessity of preheating results from thetendency of certain steels to harden in the heat affected zone, as described above. If the weldingprocess happens to be interrupted, the preheating temperature must be achieved again before wel-ding continues. It is, however, a general rule that critical seams in particular are to be welded in onepass – i.e. without interruption.

Height of the preheating temperatureThe optimum preheating temperature depends on a large number of factors. These include: thechemical composition of the base material, the welding procedure, the diameter and type of the welding consumable, the speed of welding, the thickness of the workpiece, the orientation of the welded joint on the component, the possibility of heat dissipation, the nature of the design,the external temperature, and so on. For the structural steels, fine-grained structural steels andcreep resistant steels, EN 1011-2 offers ways of calculating and estimating the preheating tempe-rature. This possibility is, however, only available within certain analytical limits. It is also possibleto estimate the preheating temperature with the aid of the corresponding time-temperature-trans-formation curve. The martensite start temperature, and the fields for the bainite stage in the pear-lite stage, provide orientation.

Performing the preheatingOnce the preheating temperature has been determined, the area that is to be welded must beappropriately heated. It must be remembered that the heat flows away into the cold material. Theheat input must be large enough for the specified temperature to be reached throughout the entirecross-section, i.e. both at the front and the back.

Relatively short seams are usually preheated with the welding torch. Special torches with air inta-ke, or fuel gas/compressed air torches are also used. In addition to preheating in a furnace, induc-tive preheating or resistance heating are also possibilities. Nowadays the latter two are preferred,since accurate control is possible here, which is essential for many materials. Notes on the size ofthe zone to be heated, and on measuring the preheating and interpass temperatures, are found inEN ISO13916.

In essence, tack welding is subject to the same quality rules as welding itself. This applies both tothe heat control (preheating) and to the selection of the welding consumable. In many cases, dueto the rapid dissipation of heat, it is advisable to preheat the workpiece even if the base materialitself does not normally necessitate preheating. Non-identical welding consumables, generally withlower strength and higher toughness, can be used, depending on the material. These tacking sitesthen usually have to be ground out at a later stage, and can only be left if a consideration of thedesign conditions allows it. Tacking sites should always be sufficiently long and thick, in relation tothe thickness of the base material, so that they can accept the internal stresses that arise in thecourse of assembly. Cracked tack welds must always be ground out.

Tack welds used for assembly aids must be removed and ground smooth.

If the materials are sensitive, the ground regions should be checked for freedom from cracks. Inaustenitic materials, the tacks must be carried out using the same conditions as the welding itself(forming). More tacks are necessary here due to the greater shrinkage.

3.5.3. Instructions for avoiding welding defects


Faults in welded joints are unwelcome, and in some cases can be the cause of very expensiverework. In many cases, faults and damage can be avoided through taking simple precautions.These precautions can be implemented at various stages in design and manufacture. They canrange from the optimum selection of welding consumable, can include proper control of the weldingprocess, and regular servicing of the electrical power source. This subsection does not give a com-plete overview of all possible welding defects, but restricts itself to types of fault that can be avoi-ded through relatively simple precautions. In addition to a description of fault of its causes, the fol-lowing tables contain possible countermeasures that can have a favourable effect. For more detai-led information, standards, welding guidelines (e.g. those of the DVS – the German WeldingSociety) and other literature can be consulted.

The occurrence and avoidance of cracksThe following list provides explanations of possible adverse effects that can occur when weldingsteels, and suggests measures for avoiding these faults. Fundamentally, the majority of the effec-ts listed can be avoided by optimising the chemical composition of the steel and of the welding con-sumable.

The list is not sorted according to the importance of the faults described.Faults and causes Counter-measures

Use of welding consumables that yield avery low hydrogen content in the weld metal.

Application of low-hydrogen annealingstraight from welding heat

HYDROGEN induced CRACKINGAtomic hydrogen diffuses into the weld metaland into the heat affected zone during welding.This can result in cracking during and after coo-ling, particularly in regions of higher internalstress and high dislocation density (e.g. at thegrain boundaries in martensite).

Selection of the optimum welding temperatu-re cycle, layer structure and/or bead geome-try.

INADEQUATE TOUGHNESSIn general, the toughness of certain parts of theheat affected zone is impaired with respect tothe base material through the formation of coar-se grains or through hardening. Unfavourablecrystallisation in the weld metal can lead to poorfigures.

Modifying the welding parameters so that theindividual beads are broader and flatter, i.e.reducing the depth-width ratio of a bead.

Reducing dilution with the base material.

Lowering the welding speed.

Note: Solidification cracks rarely occur insteels with low sulphur and phosphorus con-tents.

SOLIDIFICATION CRACKS (hot cracks)Solidification cracks are predominantly associa-ted with trace elements such as sulphur orphosphorus. These can precipitate in the centreof the bead during solidification. They are theresult of the formation of low-melting films aro-und the grain boundaries. These films reducethe ability of the weld metal to deform, and longitudinal cracks can then develop as a resultof the shrinkage stresses as the weld metal solidifies.

The occurrence and avoidance of poresIn contrast to the effects described above, the chemical composition of the base material and of theweld metal only have a small effect on the formation of pores during welding. Pores can form in twobasic ways.

Gases such as hydrogen, nitrogen and oxygen can be dissolved in liquid steel. In metallurgical poreformation, these gases precipitate as gas bubbles during the solidification process due to theabrupt change in solubility between the liquid and solid phases (H2, N2, CO, O2). If the rate of soli-dification is greater than that with which the gas bubbles rise, they are enclosed ("frozen in)", andare left behind, mostly as spherical pores in the welded seam. Depending on the amount of gasfound, these pores can also take a tubular form. Gas bubbles arise at the boundary between theliquid and solid phases and in the slag particles floating in the melt.

Mechanical pore formation occurs when cracks or cavities filled with gases – such as air – are wel-ded over. If the gases, as they expand under the influence of the welding heat, cannot completelyescape in a different direction, a pressure develops which is released through the formation of

A wide variety of various criteria must be considered in the design of a component if it is to bemanufactured economically. Above all, this means the design of the component appropriately forits function, stress, materials and fabrication. If the component needs to be implemented as a wel-ded construction, other factors, such as the cost of materials, of processing the individual parts, andthe welding costs enter into the economic consideration.

Although it is not possible to give general instructions and solutions for the economic design of wel-ded components, nevertheless a number of basic rules can be defined that make the work easierand save costs. Rules of this sort are listed below, but the sequence in which they are given doesnot necessarily correspond to their significance.

• Dimension fillet welds properlyKeep fillet welds as thin as possibleConsider the formation of the fillet weld, and exploit deeper fusion penetrationArrange for thin, long fillet weldsProvide double fillet welds were possible

• Consider accessibility

• Employ economical seam types at butt jointsApply as little weld metal as possibleBear the welding method in mind, e.g. use flux cored wireCheck the included angle of the seamCheck the effect of the material on the type of seamConsider root back-welding

• Exploit cost reduction potentials in manufactureSpecify allowed timesAnalyse the times, and look for possible savings

• Reduce the pure welding timeWhile bearing in mind the base materials, wall thickness and other parameters:

Use greater current with the same electrode diameterUse thicker electrodesUse other types of electrodeUse other auxiliary welding materialsEmploy methods with higher capacity, such as welding with

flux cored wire or SAW wire

• Select an easier welding position

• Mechanise the manufacturePartial mechanisation of the welding method usedReplace the existing method with a mechanised welding methodAdapt the joint preparation

• Use backings aids for economy and calculation

• Do not apply more weld metal than necessaryAssemble with dimensional accuracyMake more accurate flame cutsMonitor seam thickness and weld reinforcements
