Flux-cored arc welding (FCAW) is primarily used for welding thick materials and metals. These include cast iron, carbon steel, stainless steel, high-nickel alloys, and low-alloy steels for activities such as shipbuilding, bridge construction, structural steel erection, and heavy equipment repair across a wide range of heavy industries, including construction.nnThe continuously-fed tubular electrode helps increase deposition rates and improve productivity. Flux-cored arc welding is generally used for welding contaminated or dirty materials, thanks to its self-protecting properties.
