Flux-cored arc welding - Wikipedia

Flux-cored arc welding (FCAW or FCA) is a semi-automatic or automatic arc welding process. FCAW requires a continuously-fed consumable tubular electrode containing a flux and a constant-voltage or, less commonly, a constant-current welding power supply.An externally supplied shielding gas is sometimes used, but often the flux itself is relied upon to generate the necessary protection from the
