Flux-core arc welding, also referred to as dual shield welding, is a process that is similar to but more efficient than MAG welding.
Initially developed as an alternative to sticking welding, this semi-automatic arc welding process combines a constant voltage power supply, a wire-feed electrode, and MAG-like welding equipment to weld metals.
This process is compatible with cast iron, stainless steel, hard-facing alloys, and most carbon steels.
