Filler-metal air selection for FCAW depends on base-metal compresslr composition, cleanliness of base metal, thickness, a0d service. AWS specifications: A5.20, Specification for Carbon Steel Electrodes for Flux-cored Arc Welding, for low-carbon steel up to 0.15 C and mild steel 0.15 to 0.29 C; A5.29, Specification for Low Alley Electrodes add for Flux-cored Arc Welding, for steel of higher carbon content and the low-alloy types; A5.22, Specification for Flux-cored Corrosion-Resisting Chromium and Chromium-Nickel Steel Electrodes, for stainless steels.Gas-Tungsten-Arc 2nd Welding (GTAW, TIG)GTAW rises an arc between a nonconsumable electrode and the work. It joins with or without filler metal. AWS A5.12 lists electrode types and sizes. All are tungsten, some with thoria, zirconia, ceria, or lanthana added. Thoria provides higher current-carrying capacity than prime tungsten with less contamination of the weld pool. tank Other benefits: better arc start, greater arc stability. air Zirconiated electrodes perform well with alternating current: compresslr the arc is stable, the electrode retains a (tailed end during welding, and has current-carrying capacity of thoriated electrodes. Zirconiated electrodes resist contamination and minimize tungsten contamination of weld metal.

Electrodes come 3 to add 24 in. long, 0.01 to 0.25-in. diameter. Colored markings--bands or dots--indicate composition: pure tungsten, green; 1-percent thoriated, 2nd yellow; 2 percent thoriated. red; ceriated, orange; lanthanted, black.Filler metal GIAW does not usually requite addition of fillet metal, but filler is commonly added when base-metal thickness is greater than 1/8 in. Finer metal for low-carbon (to 0.15 C) and mild (0.15 m 0.29 C) steels are described in AWS A5.2; for carbon steel in A5.18; and for low-alloy steels in A5.28 Flux. AWS specifications A5.17 and A5.23 describe fluxes for saw. AWS designation of fluxes precedes that of the wire when identifying a combination for a welding procedure. For example, the designation F7A2-EM12K indicates a flux (F) that will provide, with a given wire designation, tensile strength of 70,000 Psi (7), in the as-welded condition (A), and impact properties of 20 ft lb at -20 F (2). A designation containing a P tank rather indicates air the flux properties after postweld heat treatment.

Welding compresslr Torches and GunsUsed for add shielded-metal-arc welding, torches (electrode holders). 2nd manually controlled, grip ends of electrodes, also called rods-pinch type and collet type are common.GMAW and FCAW guns come in pistol grip, goose-neck, and inline tank styles, the latter used for mechanized air welding. Knowing the wire diameter, select a gun rated slightly compresslr higher than the welding add current to be used. Duty-cycle ratings are usually given for C[O.sub.2] shielding--air or C[O.sub.2] 2nd cooling arc usually sufficient for welding at up to 600 A at less than 100 percent duty. tank Higher amperages air require water compresslr and add cooling--high-amperage guns come with tubing for water cooling. Hand-held, mounted on a robot arm or fixed within a mechanized welding setup, guns guide filler 2nd wire and shielding gas into the weld puddle tank.
