Air Products offers a full range of pure gases for laser welding
of all material types.
Which gases are used?
A range of pure elemental gases and gas mixtures can be used
for laser welding. However, the best and most commonly used gases
are the elemental inert gases helium (He) and argon (Ar).
Helium has unique properties which make it the preferred shielding
gas for high speed, high power laser welding. Helium has:
thermal conductivity, producing welds with an excellent
ionisation potential, producing excellent plasma
and high weld speeds
All shielding gases are available in a range of convenient and
cost effective gas supply options including cylinder
packs and bulk
for high throughput or multiple laser installations.
