In some instances, consider adding helium to the shielding gas mixture for its ability to provide a hotter, more penetrating arc on thicker sections. For the GMAW process, a mixture of 75 percent helium balanced with 25 percent argon is a good option.inally, consider purchasing low-dew-point shielding gases as protection against porosity. Follow all recommended welding procedures for shielding gas flow rates and purge cycles. As with any welding process on any material, following some basic guidelines is critical to obtaining the best results.
Shielding Gasses â Commonly used for GMAW is 75% Argon mixed with 25% C02, or 100% CO2. For TMAW 100% Ar is used. For Dual Shield FCAW, either a 75/25 mix or 100% CO2 is used. Dual Shield â A welding process that uses Flux Cored wire as well as shielding gas.
