MIG Welding Alloy SteelMIG welding is the most widely used process for welding a wide range of creep resisting steels, high temperature steels, low temperature steels, high manganese steels, and direct and case hardening steels. Filler wires for low alloy steels are usually selected to match the mechanical properties of the parent plate, and this usually entails matching the chemical composition as closely as possible. There are several shielding gas types available for MIG welding alloy steel. These may contain argon, helium, carbon dioxide or oxygen, such as the Argoshield range, but will not include hydrogen or nitrogen because of the inherent susceptibility of steel to these gases.
