Argon is used as a protective atmosphere for industrial processes such as steel manufacturing, welding, metal fabrication,, electronics, automotive part manufacturing, food preservation and wine making.

Argon pure gas and CO2 gas mixtures are used in shielded arc processes for welding aluminum, stainless steel, bronze, copper and carbon steels. 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 the 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. Ultra-high-purity ALPHAGAZ™ branded argon is produced in laboratories for gas chromatography, zeroing and other process-control applications.

ALPHAGAZ™ 1000 – argon in cryogenic liquid form at 99.999% purity – is employed when large volumes of gas are used with inductively coupled plasma (ICP) and Fourier transform infrared (FTIR) instruments.
