Metal Active Gas Welding (MAG) Overview

Metal Active Gas (MAG) welding is a process that uses heat created from a DC electric arc between a consumable metal electrode and a workpiece which melt together to create a weld pool that fuses to form a join. Active gas mixtures have been developed primarily for welding steels. Typical shielding gases are mixtures of argon, carbon dioxide and oxygen.
