Welding and Metal Fabrication

Argon is used to create an inert shield gas to enhance arc stability and characteristics of gas metal arc welding. It is also the primary gas for the Gas Tungsten Arc Welding (GTAW) process.

Metal Production

Used to maintain temperature and consistency of composition, argon prevents oxidation during processing. It also flushes out carbon monoxide and reduces chromium losses during the Argon-Oxygen Decarburization stainless steel refining process.

Automotive and Transportation Equipment

Argon is used in combination with other gases to weld auto parts, frames, mufflers and other automotive parts. It also provides an oxygen and nitrogen-free environment for annealing processes and is an essential component in airbags.

Aerospace and Aircraft

Argon is a versatile industrial gas used in welding applications, such as the welding of specialty alloys, and in the production of light bulbs and lasers. As an inert gas, it can also be used to provide an oxygen- and nitrogen- free environment for heat treating processes.

Cylinders & Liquid Containers

For smaller, more specialized applications, we offer argon gas in high-pressure gas cylinders and liquid argon in Dewar’s in a variety of sizes.

Bulk & Microbulk Delivery

We offer a bulk liquid delivery system with a variety of argon tank sizes and purities available to suit your operations. We also offer Microbulk on-site gas delivery as an alternative to cylinders.
