Flux-Core Welding
Arc welding using a tubular flux-filled wire for high-deposition structural and heavy fabrication.
0 companies
Flux-cored arc welding (FCAW) uses a continuously fed tubular wire filled with flux to shield the weld pool. It combines the speed of MIG welding with the ability to weld outdoors and on dirty or rusty materials, making it popular for structural and heavy fabrication.

Flux-Core Welding FAQ
What is the difference between flux-core and MIG welding?
Flux-core welding uses a tubular wire with flux inside, while MIG uses solid wire with external shielding gas. Flux-core can be used outdoors without gas (self-shielded) and generally provides higher deposition rates on thick materials.
