What is Argon?

Argon (Ar) is an inert colorless, odorless, tasteless, non-corrosive, non-flammable and non-toxic gas.

We offer compressed and liquid argon in various grades specific to different applications, such as:
• A shielding gas for welding or producing reactive metals
• An atmosphere for electronic manufacturing
• A carrier gas for chromatography
• A fill gas for specialized lamps
• An atmosphere for growing silicon or germanium crystals
• Graphite furnace atomic absorption

Industrial Applications

Manufacturing & Metal Fabrication
Argon is a welding shielding gas that enhances arc stability and prevents atmospheric contamination of welding pools. Argon is essential to gas tungsten arc welding (GTAW). It also prevents oxidation during metal production.

Aerospace & Defense
Argon is vital for welding special alloys and for various welding applications. It is essential for laser and light bulb manufacturing. In heat-treating applications, argon is used to create inert environments free of oxygen and nitrogen.

Beverages
Denser than air, argon is used for blanketing wine and flushing oxygen from containers.

Fleet-Based Commercial Services
Used in MRO applications, argon is a vital gas for welding automotive parts and plasma arc gouging.
