Flux core welding uses a tubular wire filled with flux. During welding, the flux releases gas and slag that shield the molten pool from contamination. This protection keeps the weld stable, even in windy or dirty environments. There are two main types of flux core welding: Self-Shielded (FCAW-S), which doesn’t require external gas, and Gas-Shielded […]
