Use of argon and liquid argon in various industries

Aerospace

Argon is a widely used industrial gas, which is often used in welding operations such as special alloys and in the production of light bulbs and lasers. As an inert gas, argon can provide an oxygen-free and nitrogen-free environment for the heat treatment process.

Automotive and transportation equipment

Argon can be used with other gases to weld automotive parts, frames, mufflers and other automotive parts. It can provide an oxygen-free and nitrogen-free environment for the annealing process, and is also an important part of airbags.

Metal production

Argon suppresses oxidation during processing, thereby maintaining temperature and composition stability. It can also remove carbon monoxide and reduce chromium loss during the refining of argon-oxygen decarburized stainless steel.

Welding and metal processing

Argon is an inert protective atmosphere that enhances the arc stability and characteristics of gas-shielded metal arc welding. In addition, argon is the main shielding gas for tungsten arc welding (GTAW) processes.
