Alulinx® Weld Process Gas

One gas that does it all for aluminium and its alloys

A multi-purpose shielding gas specifically designed for high-quality welding of aluminium and its alloys. Alulinx® weld process gas has been specifically designed as the only gas that you need for the high-quality welding of aluminium and its alloys. If you aim for the most exacting standards, you will need a dedicated gas like Alulinx® weld process gas.

Alulinx® weld process gas gives superb weldability, combined with high welding speeds, up to 35% faster than is possible with argon, as well as promoting safety through low ozone generation.

​Alulinx® Weld Process Gas Gives Superb Weldability.

Combined with high welding speeds, up to 35% faster than possible with argon, as well as promoting safety through low ozone generation.

When you aim for the highest standards the elimination of weld metal porosity can be a problem. Alulinx® Plus gas with its controlled addition of helium is all that you need to give you the edge.

How Can Alulinx® Weld Process Gas Help When Welding Aluminium?​

Improved Productivity

An increase in manual weld speeds of up to 24% in MIG welding and up to 35% in TIG welding when compared with argon.

Fewer Rejects

Ultra low porosity levels and excellent fusion characteristics. This improves weld quality and means fewer rejects.

Improved Working Environment

Protecting the work environment with minimal ozone generation

Ask the Expert

“I want to increase my speeds, but not sacrifice quality – is this possible?”

Our Alulinx® Plus gas increases speeds and quality too. For example in 20 seconds you could TIG weld 50mm compared to 30mm with pure Argon.
