Mig (GMAW) &Tubular Wires (FCAW)
Mig welding (GMAW) is a semi-automatic or automatic arc welding process that uses a continuously-fed consumable wire and constant-voltage. FCAW is an alternative to shielded metal arc welding (SMAW) when high deposition rates are required.
Some Gas shielded and Flux Cored Wires can be used to weld through rust, mill scale, and light oil without pre-cleaning. You can use Self-shielding flux-cored Tubular Wires to weld carbon and stainless steels. Hardfacing Tubular Wires can be used to restore dimensions of worn surfaces. And, you can use Tubular Wire to join most types of mild steel.
