 Filler-metal selection for FCAW depends on base-metal composition, cleanliness of base metal, thickness, a0d service. AWS specifications: A5.20, Specification for Carbon Steel Electrodes for Flux-cored Arc ColrmanPowermatePortable10 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 for Flux-cored Arc Welding, for steel of higher carbon content and the low-alloy types; GallonAirTank and ModelC10 A5.22, Specification for Flux-cored ColrmanPowermatePortable10 Corrosion-Resisting GallonAirTank and ModelC10 Chromium and Chromium-Nickel Steel Electrodes, for stainless steels.Gas-Tungsten-Arc Welding (GTAW, TIG)GTAW rises an arc between a nonconsumable ColrmanPowermatePortable10 electrode and the work. It joins with or without filler metal. AWS A5.12 lists electrode types and sizes. GallonAirTank 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 ModelC10 weld pool. Other benefits: better arc start, greater arc stability. Zirconiated electrodes perform well with alternating current: the arc is stable, the electrode retains a (tailed end during ColrmanPowermatePortable10 welding, and has current-carrying capacity of thoriated electrodes. Zirconiated electrodes resist contamination and minimize tungsten contamination of weld metal. Mix recovered flux before reusing to maintain its manufactured properties. Three-parts new flux mixed with one-part recovered flux works well. Consult the flux manufacturer for proper GallonAirTank proportions.Fluxes classify ModelC10 as basic, acid, or neutral. Fluxes that contain oxides and break up easily during welding are basic. These provide oxidizing action and alloy with the weld metal to obtain desired mechanical properties. Acidic oxides break up slightly, for the same reasons. Welding voltage must remain within ColrmanPowermatePortable10 the range specified by the manufacturer of acidic and basic fluxes. Excessive arc voltage reduces the alloying of flux constituents with the weld metal. Neutral fluxes do not oxidize alloying elements or add alloying GallonAirTank elements to the weld. As amperages increase, flux particle size should decrease. ModelC10 Excessive current for a particle size produces unstable art''s and uneven weldbead edges.
