WELDING

THE VARIOUS ELECTRIC WELDING PROCESSES

GUIDE TO WELDING SHADES

Arc welding is a generic term for a process during which an electric arc is created between an electrode and the parts to be assembled.

• Electric welding, a trade for expertsWelders carry out assembly by melting or applying filler metal to sections or elements of various parts using an electric arc or other welding processes (coated electrode, TIG, MIG, MAG) and the appropriate equipment (welding station, welding set, etc.). Manual skill is one of the most important factors of the process.

• Electric arc welding with coated electrodesThis is the best known welding process.When the coated electrode approaches the parts to be assembled, an electric arc is created which releases strong heat causing the electrode to melt.Coated electrodes: for welding carbon steels or light alloy steels - for welding stainless steels.

• Arc welding with non-consumable electrodes: TIG weldingThe electric arc is created between the sheet metal to be welded and a non-consumable W electrode protected by an inert gas (Argon or Helium). TIG stands for "Tungsten Inert Gas" where "Tungsten" refers to the electrode and "Inert Gas" the type of plasma gas used. This welding process falls into the category of arc welding processes with a non-consumable electrode. The arc is created between the refractory electrode (- of the generator) and the part (+ of the generator) under a gaseous flux; generally, it is a rare gas or a mixture of rare gases. T.I.G. welding is especially used for welding thin sheet metals, but more particularly for all metals that are difficult to weld. These metals include aluminium, magnesium, stainless steel, copper and its alloys, and carbon steels of various thicknesses.• Tungsten electrodes with a 1% to 2% thorium content are

particularly used for welding light alloy steels (soft steel). This type of electrode requires lower amperage.

• Tungsten-zirconium electrodes have the highest melting point and are most frequently used for welding aluminium.

standards• Process 141 according to ISO 4063

• Arc welding with consumable electrode wire: MIG-MAG weldingMIG-MAG welding is a semi-automatic welding process. The protective atmosphere differs according to the type used, i.e. MIG or MAG: • for MIG Metal Inert Gas, helium, argon

or a mixture of both is used• for MAG Metal Active Gas, a mixture of argon

and carbon dioxide is used. Only steels can be welded with this type of active protection. For MIG, the gas is inert, i.e. it does not react with the metal. For MAG, however, the gas must react with the metal and therefore be active.

Equivalents:• Metal Inert Gas• Metal Active Gas• GMAW: Gas Metal Arc Welding (uses a solid electrode wire)

according to American standards• FCAW: Flux Core Arc Welding (uses tubular wire, a so-called

"flux-cored" wire) according to American standards• Process 131 (MIG) or 135 (MAG) according to ISO 4063

• Plasma weldingPlasma welding is an automatic welding process. Plasma defines the high energy state generated by the creation of an electric arc with an orifice or nozzle. The Plasma process is a major technological breakthrough involving constricted arc welding with inert gas (TIG process). Plasma welding is essentially used for stainless steels, metals and noble alloys.PAW: Plasma Arc Welding according to American standards

ACTIVE FILTERS, "INTELLIGENT" TECHNOLOGYActive welding filters provide reliable protection. Whether in a clear or darkened state, they ensure permanent protection against UV/ IR emissions, heat, sparks and projections. The filter’s degree of protection is defined to avoid "blinding" by the electric arc.

Active welding filters must always be used with a welding helmet.

When an electric arc is struck, the active welding filters automatically darken and when the arc is extinguished, they return to their initial clear state. So the active welding filters free up the welder’s hands and therefore save time, reduce fatigue and greatly improve quality thanks to better arc positioning.These filters must be protected by an outer and inner polycarbonate screen guard.

Active Technology, high-tech filers for optimum protection.

Bollé Safety protects all eyes The eye is a delicate and sensitive organ. There are many types of eye injury with severity ranging from simple irritation to total blindness. This is why it is so important to be aware of all potential risks in the workplace. Protecting eyes is our business; ensuring unbeatable product quality is our motto!

Unprotected electric arc welding is dangerous It can lead to painful inflammation of the cornea and irreversible opacity of the eye’s crystalline lens, known as a cataract. Our line of products is entirely researched and designed to meet current standards and your expectations in terms of comfort and style. Our team of specialists will help you find the best solution for your risks.

Bollé Safety traceabilityProduct and batch identification ensures product quality control upstream in the distribution chain. This tracking is part of the Bollé Safety approach to constantly improve its product offering, quality, service and overall company efficiency.

Bollé Safety guarantees reliable and comfortable products All products marketed by Bollé Safety comply with current European standards. Helmets from the range are guaranteed on average between one and three years. For safety and standard requirements, the auto-darkening filters must be protected by an inner and outer screen guard. No warranty will be given for damaged filters, used without protective screen guards. The consequences of incorrect use are not covered by the warranty.

Products certified for your safetyAll Bollé Safety products comply with European directive 89/686/EEC, EN175 and EN379.

EN379, standard for filtersEN379 belongs to a series of European standards drafted by the European Standardization Committee (ESC) within the scope of the application of the European Directive on Personal Protective Equipment (PPE). It specifies the requirements relating to welding filters which automatically switch their transmission factor in the clear zone to a lower value when a welding arc is struck (known as welding filters with switchable scale numbers). The specifications of the standard apply if such a filter is to be used for continuous observation of the welding process and if it is only used during the period when the arc is struck. The standard also specifies the requirements for welding filters with different welding scale numbers in the clear zone (called welding filters with a double scale number). These filters are used for welder protective eyewear or system-mounted protection.

EN175, standard for helmetsEN175 specifies safety requirements and test methods related to eye and face protective equipment used for welding and associated techniques. This European standard specifies the requirements and test methods related to personal protective equipment used to protect the operator’s eyes and face against harmful optical radiation and other specific risks due to customary welding or cutting processes or other associated techniques. The standard specifies protection, including ergonomic aspects, against various risks or hazards including radiation, fire, mechanical and electrical risks. This standard defines the terms used and specifies the requirements related to materials, design and manufacture.
