Flux-Cored Arc Welding - (FCAW). Flux-cored Arc Welding is a welding process similar to GMAW, in that it uses a continuously fed electrode, but uses a tubular wire filled with flux instead of a solid wire. There are two types of flux-cored wire, self-shielded and dual shield.
MIG vs TIG Welding. MIG and TIG welding are two types of arc welding, using metal electrodes and an inert gas as the shielding from oxidation at high temperatures. Both types of welding are relatively easy to learn, and the welding processes can be performed on all the common materials.
