Laboratories and Research

Air Liquide has a dedicated range of laboratory gases. For your helium needs, we offer pure helium under the ALPHAGAZ brand.  ALPHAGAZ™ 1 grade of pure helium has a minimum purity of 99.999%. ALPHAGAZ™ 2 is ultra-pure at a minimum of 99.9998%, perfect for critical laboratory and analytical applications. Our ALPHAGAZ™ compressed gas cylinders are equipped with the SMARTOP™ cylinder top; a cylinder top with a built-in contents gauge, easy on/off lever and built-in flow moderator (flow restriction valve.)

Welding and Laser Cutting

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, 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 is ARCAL and LASAL.  Please visit the dedicated pages for ARCAL™ and LASAL™ for more information, or contact us and a specialist will help identify the gas that best suits your process.
