Shielding & Industrial Gas Mixtures


Shielding Gas Mixtures

Looking for the right shielding gas for your application?

WestAir developed the CoverShield  line of proprietary blends of shielding gas for MIG and TIG to help you optimize your welding results. Shielding gases protect the finished weld from the effects of oxygen and nitrogen, and can positively affect weld-metal properties (e.g., strength, corrosion resistance and toughness).

CoverShield MIG gas mixes can also improve the weld bead shape and size as well as the weld porosity and fusion. The right shielding gases can increase your productivity with increased travel speeds and by minimizing the amount of spatter and clean up.

Please refer to the table below for information and to access safety data sheets on mixes available from WestAir.
