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.
In addition, smaller-diameter wires can be used in all positions. FCAW can be used with or without shielding gas; if you use shielding gas, carbon dioxide is very cheap. (Other gases, such as 75/25, also can be used.) The flux contains oxidizers, so the base metal needs minimum cleaning before a weld is made. Postweld cleanup is a breeze because the slag chips off very easily.
