Argon

Air Liquide supplies argon and argon gas mixtures in various volumes and purities. Argon is used as a protective atmosphere for a large number of industrial processes, including steel manufacturing, welding and metal fabrication, electronics,food preservation and winemaking. Argon is also used in fluorescent lighting applications and serves as a non-reactive thermal blanket in double glazed windows.

Argon pure gas and argon gas mixtures are commonly used in shielded arc processes for welding aluminum, stainless steel, bronze and copper. 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 changes that would be detrimental to the weld. In steel manufacturing, argon prevents interaction between liquid metal and the surrounding atmosphere.

Air Liquide offers ARCAL™ brand pure argon and gas mixtures, with four ready-to-weld products that cover practically any welding application. Each one is designed to be easy to use, reliable and efficient, when and where you need it. In laboratories, ultra-high purityALPHAGAZ™ brand argon is engineered for gas chromatography, zeroing and other analytical and process control applications. ALPHAGAZ 1000, which is argon in cryogenic liquid form at 99.999% purity, is useful when large volumes of gas are needed for use with ICP and FTIR instruments.
