High-argon wire welds

Advancements in FCAW

May 11, 2011

Flux-cored welding is growing in popularity, yet its dependence on high concentrations of CO2 has prevented fabrication shops that employ a bulk gas delivery system from using the process. Recently wires have been developed that utilize a higher content of argon and a lower content of CO2. The result is a wire that provides low spatter, less welding fumes, and higher out-of-position deposition rates, as well as excellent weld characteristics in the vertical and overhead positions.
