Return to welding history

Flux-cored arc welding (FCAW) is a common 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. The use of an externally supplied shielding gas is optional creating the primary process variation:
