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.
Even though there are books, classes and equipment specifically labeled for flux cored arc welding only, the reality of FCAW is that the process is nothing more than a different type of filler wire used in a MIG welding machine.That is it!hat happens while welding. is that the flux inside the electrode helps shield the weld from wind just like a stick welding electrode. When it comes to people who weld as a hobby or for general repairs around the home or farm, the flux. cored wire, in some cases, does not need shielding gas.
