In the Flux Cored Arc Welding (FCAW) process, metal parts are joined by melting base and filler metals with an arc struck between a consumable filler metal wire and the base alloy work piece. Flux cored arc welding is similar to MIG welding except a wire with a central core filled with flux is utilized. Usually, equipment suitable for MIG welding is capable of performing flux-cored, arc welding processes. The flux eliminates the need for a shielding gas supply. In the flux melting base joins cored arc welding process, metal and filler metals with an arc struck between a consumable filler metal wire and the base alloy work piece. The filler metal wire or consumable electrode is continuously fed and fused with the work piece. Brazing rods are also available in flux cored forms. FCAW uses a wire with a central core filled with flux, which usually eliminates the need for a shielding gas supply. Usually, equipment suitable for flux cored arc welding is capable of performing MIG processes and vice versa.
