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.
Porosity, as can be seen on the face and interior of the weld bead, can be caused by inadequate shielding gas and can dramatically weaken the weld. Carbon Dioxide (CO2) is the most common of the reactive gases used in MIG welding and the only one that can be used in its pure form without the addition of an inert gas. CO2 is also the least expensive of the common shielding gases, making an attractive choice when material costs are the main priority.
