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.
Laser Types Each type of laser used in welding applications has positives and negatives and different cost structures. Some applications can be performed by any laser; some are so complex or specialized that only one type of laser is appropriate. The most common types today are CO 2, Nd:YAG, fiber, and disk lasers.
