A: I would like to answer your question as a general discussion of flux-cored welding. The American Welding Society (AWS) classifies all tubular electrodes having a flux on the inside as flux-cored wires, and calls it the Flux Cored Arc Welding (FCAW) process. All flux-cored wires have some similar characteristics. These include forming a protective slag over the weld, use a drag angle technique, have the ability to weld out-of-position or flat and horizontal only at higher deposition rates (depending on type of wire), ability to handle contaminants on the plate, etc.
FCAW FCAW stands for Flux Cored Arc Welding. The flux of the welding wire is in. the center of the electrode instead of on the outside. The process requires wire. feed spools and cable. The rod is pushed through the center of the cable and. through the welding gun. Shielding gas may or may not be used depending on the. flux material in the core of the wire. FCAW has the advantage over SMAW for all. position welding and the speed of welding since the wire is continuously fed.
