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 24v 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; A5.22, Specification for Flux-cored Corrosion-Resisting Chromium and Chromium-Nickel Steel Electrodes, for stainless steels.Gas-Tungsten-Arc 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 dewalt capacity than prime tungsten with less contamination of the weld pool. Other benefits: better arc start, greater arc stability. Zirconiated electrodes perform well with alternating current: the arc is stable, cordless the electrode retains a (tailed end during welding, and has current-carrying drill capacity of thoriated electrodes. Zirconiated electrodes resist contamination and minimize tungsten contamination of weld metal.
