 Filler-metal selection for FCAW depends on base-metal composition, cleanliness of base metal, thickness, a0d ballfalve 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 ballfalve for Low Alley Electrodes for Flux-cored Arc Welding, for steel of higher carbon content and the low-alloy types; A5.22, Specification ballfalve for Flux-cored Corrosion-Resisting ballfalve 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 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, the electrode retains a (tailed end during welding, and has current-carrying capacity of ballfalve and ballfalve thoriated electrodes. Zirconiated electrodes resist contamination and minimize tungsten contamination of weld metal. Features and OptionsPower supplies are capable to "talk to each other," useful when a company" ballfalve wants to input the same welding procedures into several machines at once or monitor the welding consistency and performance of several machines from a single location-through serial-data ballfalve communications. Fabricators can ballfalve and ballfalve take some of their machines and connect them to a personal computer to monitor performance, and download welding parameters to the machines from it memory card for fast setup. High-end machines will calculate the pounds of weld wire used per machine. The machine can also be prepped to constantly monitor and average the welding current and voltage used, so that fabricators can set limits on the machine and track how many times welding parameters fell in or out of these limits.
