Alumaxx® gas – our best gas for welding aluminium
Alumaxx® Plus shielding 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’ll need a dedicated gas like Alumaxx® Plus shielding gas. A multi-purpose shielding gas, it is specially designed for MIG and TIG welding aluminium and its alloys across all material thickness.
Alumaxx® Plus shielding 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.
Just look at the advantages:
When you aim for the highest standards the elimination of weld metal porosity can be a problem.
Alumaxx® Plus gas, with its controlled addition of helium, is all that you need to give you the edge.
Improved productivity
Alumaxx® Plus shielding gas gives you 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
Alumaxx® Plus shielding gas is easy to use, gives ultra low porosity levels and excellent fusion characteristics. This improves weld quality and means fewer rejects.
A better working environment
As ozone is a health hazard which cannot always be fully removed by fume extraction equipment, Air Products has concentrated on developing the Maxx® range of welding gases, which give lower ozone exposure levels. The result – a gas that provides a better working environment as well as improved productivity and fewer rejects.
All of the ozone measurements are simulated “real” exposure measurements and were carried by leading independent laboratories.*
*All of the ozone measurements were carried out by independent accredited laboratories. All tests were made under controlled “real” working conditions in accordance with EN/ISO 10882-2.
Ozone exposure is the key measure as it simulates the amount of ozone that a welder will be exposed to during his normal working day. It is measured behind the welding helmet during welding and is also taken at a fixed point located 250mm horizontally and 250mm vertically from the arc.
Ozone levels are measured using a chemiluminescence analyser.
All of the reported work was carried out at TWI, Cambridge, UK (www.twi.co.uk)
The occupational exposure limit for ozone is low and varies by country. The limit of exposure in the UK is 0.2ppm ozone for a 15min reference period. |
