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.
Air Liquide supplies pure argon and argon mixtures in various volumes and concentrations, as well as bulk volumes (1,5 metric tons per month or higher) of high purity Argon. As part of our bulk argon supply solutions, we install argon storage vessels at customer facilities and can monitor supply levels to ensure deliveries are scheduled as needed. Our supply network includes deliveries via pipelines and customer deliveries via truck. We supply smaller quantities of pure argon and CO2 gas mixtures in high-pressure compressed gas cylinders and bundle packs of compressed gas cylinders. Air Liquide offers a wide range of services to meet each customer's needs.
