Helium

Inerting, cooling and welding for your industry

Safety Data Sheet (SDS)

Air Liquide offers industrial helium for the hospitality and laboratory markets, however, it is also used in mixtures for applications such as welding and laser cutting.

Welding and Laser Cutting

industrial helium is widely used in the steel manufacturing industry as an inert shielding gas for arc welding and in laser applications. It is utilised both as a pure gas and in mixtures with argon for TIG or MIG welding. In some applications, industrial helium has an advantage over argon in gas-shielded arc welding because it provides greater arc heat for the same welding currents and arc length. This results in deeper penetration, which is preferable for welding heavier materials that require greater welding speed or when metals of high thermal conductivity are to be welded.

Our solution

For your welding or laser needs, ARCAL™ and LASAL™ are a perfect solution depending on your task.

Party Helium

We offer industrial helium in a range of cylinder sizes to accommodate your needs, from ultra small portable containers with easy to use valves through to large volume cylinder packs for commercial applications. We have a size that will fit your requirements.
