Shielding gas protection. Shielding gases for MIG/GMAW welding. The basic gas for MIG/MAG welding is argon (Ar). Helium (He) can be added to increase penetration and fluidity of the weld pool. Argon or argon/helium mixtures can be used for welding all grades.
Usually, gas mixtures for MIG welding is a blend of carbon dioxide and argon. The main job of the shielding gas is to cover the mouth of the weld and keep it from coming in contact with oxygen and nitrogen and the surrounding air, but these gases also affect the characteristics of the arc itself.
