Argon

A safe and reliable supply of pure argon and argon gas mixtures

Overview

Air Liquide supplies argon and argon 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 and automotive parts manufacturing, and food preservation. 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.
