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.
Different materials are better suited for certain types of radiation than others, as determined by the interaction between specific particles and the elemental properties of the shielding material. General Shielding Properties. Radiation shielding is based on the principle of attenuation, which is the ability to reduce a waveâs or rayâs effect by blocking or bouncing particles through a barrier material. Charged particles may be attenuated by losing energy to reactions with electrons in the barrier, while x-ray and gamma radiation are attenuated through photoemission, scattering, or pair production.
