  • How does flux cored arc welding ( FCAW ) work?

    This arc is struck between the metallic workpiece and the continuously-fed tubular cored consumable filler wire, with both the wire and the metallic workpiece melting together to form a weld joint. This is similar to MAG welding, except that FCAW welding uses a hollow, tubular electrode filled with flux rather than a solid metal electrode.
