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 other areas of manufacturing, the goal may be simply to limit the use of helium. Lyttle pointed out the use of a CO2 laser for welding applications as an example. Traditionally, helium is used as a shielding gas in CO2 laser welding, but it is supplied in a less-than-efficient manner to the area.
