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.
SMAW, or stick welding, is the most common form of arc welding. In the process, a stick or electrode is placed at the end of a holder. Using electricity from the power source, an arc is struck between the tip of the electrode and the metal welding surface. The heat of the arc melts the tip of the electrode creating the filler material that is deposited as the electrode is consumed.
