Argon as a shielding gas for welding

Argon pure gas and CO2 gas mixtures are used in shielded arc processes for welding aluminum, stainless steel, bronze, copper and carbon steel. Used as a shielding gas in arc welding, root shielding and plasma cutting applications, argon provides an inert atmosphere to prevent oxidation or other chemical/metallurgical changes that would be detrimental to the weld.
Air Liquide offers ARCAL™ brand of high purity argon and CO2 gas mixtures, with four ready-to-weld products that cover practically any welding application which is easy to use, reliable and efficient.
In stainless steel manufacturing, argon prevents interaction between liquid metal and the surrounding atmosphere.
Beverages

Argon is used to inert wine to prevent oxidation during winemaking.
Electronic components
Food

Argon allows to extend food shelf life with a modified atmosphere
Glass

Argon avoids corrosion of the tungsten filament in light bulbs and consequently blackening of the bulb by atmosphere inerting. Argon is used to increase thermal isolation performance of double glazing windows.
