Airgas® Industrial Welding Shielding Gases are protective gases commonly used in several welding processes to prevent atmospheric contamination of the weld pool.
Airgas operates its own dedicated blending facilities as well as maintains a national network of blending technology to ensure accurate, consistent production.
Applications
Helium is often used as a Shielding Gas in Welding, for its inert properties such as providing ideal arc temperatures for welding materials with high-heat conductivity.
In heat-treating processes, during manufacturing or metal fabrication, Helium is added to furnace atmospheres to produce stronger, more durable parts.
Helium at cryogenic temperatures is essential for operating MRI and NMR machinery.
Helium is required for determining sample content and characteristics as a carrier gas in gas chromatography.
In retail, Helium is used to give balloons a lift.
Safety
