Our solutions from laser to TIG welding

For over 100 years, the gases used for welding have been at the core of Air Liquide's offerings. Over time, our technologies and knowledge have evolved to meet the changing needs of our customers. We continually adapt our gas solutions to meet the challenges of metal fabrication and assembly manufacturing processes.

Welding at a glance

Welding joins work pieces, usually metals, by melting their edges so that they fuse together. The main process is arc welding. For this process, a gas is required to shield the liquid thread from ambient air. Argon-based mixtures are the main shielding gases in industry.

Our offer

In addition to argon-based blends, our range of premium gases can help you weld better:

  • ARCAL™ for arc welding (TIG/MIG or MAG processes).

We also have a global network of hundreds of welding and cutting specialists who help customers with programs aimed at reducing the cost of operations and optimizing quality and speed.

Air Liquide has all-in-one solutions that combine gas, process expertise, and application technologies with a commitment to performance. Our solutions are designed to optimize welding quality and costs through the use of a combination of inert gases (argon, helium or a mixture of both) and innovative nozzles.
