Submerged Arc Welding
Austenitic Stainless Steels
1. Introduction
Submerged arc welding (SAW) can be effectively applied to the fabrication of austenitic stainless steels, combining fast deposition of high quality weld metal with mechanised process efficiency. SAW is a highly productive alternative for joint filling on:
- circumferential or longitudinal seams which can be welded in the flat position (ASME, 1G; BS EN, PA)
- pipework or vessels in excess of approximately 200mm (8in) diameter, which can be rotated.
- material in excess of approximately 15mm (0.6in) thickness
SAW is conventionally utilised for joint filling on top of initial root welds made using the TIG/GTAW and MMA/SMAW processes, the latter principally for additional deposit
thickening up to 10-12mm (0.4-0.5in) to avoid ‘burn-through’ and/or single-side weld underbead thermal damage. For plate, or large diameter vessels with access from both sides, a double sided SAW procedure can be used, with back grinding or gouging, which
overcomes the need for TIG/MMA root runs.

2.2.1
SS300
SS300 is a basic non-alloying agglomerated flux with basicity index of ~1.6. This is a new flux being predominantly used with the standard 300 series stainless steel wires such as
308S92, 316S92 and 309S92. This flux will generally result in a minor loss of Mn (~0.3%) and Cr (~0.3%) and a slight pick-up of Si (~0.15%), see Table 1. SS300 is designed
specifically for the butt welding of stainless steels, where high integrity and good mechanical properties are required. Designed for DC/AC with wires up to 4mm diameter and ~700A. However wires normally are available in 1.6, 2.4 or 3.2mm diameter which
restricts current to a maximum of ~600A.

2.2.2 SSB
SSB is a basic non-alloying agglomerated flux with basicity index of ~2.2. It is a long
standing Metrode flux and one that has been recommended for use with most stainless steel wires in the past. This flux will generally result in a minor loss of Mn (~0.3%) and Cr
(~0.3%) and a slight pick-up of Si (~0.15%), see Table 2. It is designed specifically for the butt welding of stainless steels, where high integrity and good mechanical properties are required. Designed for DC+ only with wires up to 4mm diameter and ~750A. However
wires normally are available in 1.6, 2.4 or 3.2mm diameter which restricts current to a maximum of ~600A.
With the introduction of the SS300 flux, SSB is now mainly recommended for use with duplex, ER329N, and superduplex, Zeron100X®, wires.

The flux usage allowed for on a weld is normally about1½ times the weight of wire. The actual amount of flux consumed in making a weld is actually less than this and will vary with voltage. Flux consumption for SSB flux on DC+ polarity is shown in the following

2.2.3 LA491
The third flux, Metrode LA491, is an agglomerated fluoride-basic flux with a basicity index
of ~2.7 and particle size of 0.2 – 2.0mm. It can be used with most 300 series stainless steels e.g. 308S92, 316S92 and 309S92, and also duplex (ER329N) and superduplex (Zeron 100X®). Though, it is not recommended for stabilised stainless steels (321/347) because
the Ti/Nb affects slag release. Designed for DC+ or AC with wires up to 4mm diameter and ~800A. The LA491 flux also has a secondary use which is for welding with the ER308LCF
and ER316LCF wires for LNG projects and other applications requiring cryogenic properties; further information can be found in the technical profile on LNG. The LA491 flux results in a similar Cr loss to SSB (~0.3%), a slightly lower Si pick-up (~0.10%) and very little Mn loss
(~0.1%). It deposits low diffusible hydrogen containing weld metal making it suitable for thick section joint.

L2N
The final flux, L2N is a neutral, calcium silicate, fused flux with a basicity index of ~1.3. It is the only fused flux in Metrode’s range, which is virtually immune to absorption of moisture
and provides excellent slag release. The flux is specifically designed for welding austenitic stainless steels and shows a Cr loss of ~0.5%, silicon pick-up of ~0.3% and manganese
loss of ~0.35% with a 1%Mn with 316S92 wire. It can be used with DC+, DC- or AC though DC+ operation is preferred. Though it is suitable for single or multi-wire, with a current carrying capacity of 900A, for some alloys and applications smaller wires and lower currents
may be preferable to minimise the risk of hot cracking.

4. Joint Configuration
Table 6 details typical joint configurations appropriate to SAW of thicker section material, designed to facilitate root access whilst minimising joint volume and facilitating maximum productivity.
© Metrode Products Ltd Page 6 Issue 2 September 2012
With wall thicknesses up to approximately 20mm (0.8in), conventional single V-joint configurations are recommended, for wall thicknesses above 20mm (0.8in) compound V or U configurations are recommended. With double-sided welding applications, based on twin
V- or U- grooves, fabricators may opt for modified root configurations to dispense with TIG in favour of MMA (or MIG/FCW) for initial weld runs.
With any single-sided joint configurations it is important that sufficient weld thickness is deposited using TIG, MMA MIG or FCW before using SAW to avoid burning through. The actual thickness of weld deposit required in practice will vary depending on the wire
diameter and current to be used for SAW but will normally be a minimum of three runs (one TIG and two MMA for example) producing a deposit thickness of about 10mm.

5. Welding Parameters
The following guidelines are based on typical fabrication experience:
Wire diameter:
2.4mm (3/32in) diameter is the most commonly used size; 1.6mm
(1/16in), 3.2mm (1/8in) and 4mm (5/32in) diameter are also available in some grades.
Welding current: DC+ polarity is normally used; the LA491, L2N & SS300 will also
operate on AC. It is important to select the correct current. A current which is too low produces an unstable arc; as the current is
increased, penetration increases but excessive current can produce undercut or excessive bead reinforcement. Typical currents for different wire diameters are as follows:
Diameter mm
Range A
Typical A
1.6 200 – 350 250
2.4 250 – 450 350
3.2 300 – 500 400
4.0 400 – 600 500
© Metrode Products Ltd Page 7 Issue 2 September 2012
Arc voltage: Careful control is recommended to optimise weld bead geometry (eg depth/width ratio <1) and avoid risk of centreline solidification cracking. As voltage is increased a wider, flatter weld bead is
produced. Typical voltages for different wire diameters are:
Diameter mm
Voltage
1.6 27 – 31
2.4 28 – 32
3.2 29 – 34
4.0 30 – 35
Travel speed: Typically 350-450 mm/min (16-20in/min), though speeds upwards
of 650mm/min (26in/min) may be required to maintain bead shape control with smaller diameter components, eg 150mm (6in)
diameter pipe.
Electrode extension:
20-25mm (0.8-1in); < 20mm (1in) ‘stick-out’ risks loss of effective Joule heating effect and stable metal droplet detachment resulting
in arc instability and uneven, erratic weld beads. > 25mm (1in) leads to excessive resistive heating and imbalance in weld
deposition/penetration relationship.
Flux pile depth: 25-30mm (1-1.2in); < 25mm (1in) risks arc flaring through flux cover, arc/weld pool instability, possible entrainment of air into the
arc cavity and incidence of weld porosity. > 30mm (1.2in) flux pile may inhibit release of gases generated during welding and cause
weld surface porosity or ‘gas flats’.
Electrode angle: 90° for all weld runs, ie no angling in towards sidewall. With circumferential butt joints, wire should be positioned 25-30mm (1-
1.2in) before top centre and angled back along a line intersecting the pipe central axis.
Weld sequence: Weld deposit layers composed of 3 rather than 2 (wider) beads, symptomatic of higher arc voltage, are recommended to avoid risks of solidification cracking.
Flux control: Flux used must be maintained in a reliably dry condition, ideal
storage conditions are <60%RH and >18°C (>65°F). Whilst flux
from freshly opened drums, which have been stored correctly, may
be used without prior baking, it is recommended that all flux be incorporated in a system that routinely re-bakes flux for a minimum
of 1 hour at 250-400°C (450-750°F). Welding with flux hotter than
150°C (300°F) should be avoided to ensure satisfactory operation.
General requirements for flux handling are shown in Figure 2.

With repeated handling and recycling of agglomerated flux,
excessive build-up of fine particles and a shift in grain size balance ultimately leads to deterioration in operating characteristics. To
counter this effect, recycled flux should be routinely diluted with new flux on a 1:1 ratio.
Packaging: Metrode fluxes are supplied in sealed moisture resistant metal
drums with a drum weight 25kg for SS300 and 20kg for LA491, L2N & SSB.

Preheat: Whilst preheat is not normally required, initial weldment
temperatures < 5°C (<40°F) should be avoided and weld surfaces
should be clean and dry. With thick section material, preheating to
temperatures up to 100°C (200°F) may be considered beneficial in
reducing weld solidification rate to assist release of gases generated and further minimise incidence of weld porosity, particularly with
initial SAW weld runs.
Interpass temperature:
This should be measured using a contact pyrometer, at the precise start point of each run. For standard austenitic stainless steels, a
maximum interpass temperature of 250°C (450°F) should be used.
