Another welding consumable mainly utilized in flux-cored arc welding (FCAW) and gas metal arc welding (GMAW) is metal-cored wire. It is made out of a hollow metal sheath that is occasionally filled with fluxing agents, metallic powders, and alloys. Metal-cored to flux-cored wires, metal cored wires are more concerned with offering improved mechanical qualities and deposition rates than with having a large amount of flux.
