Argon

Lasers are capable of heating specified areas very rapidly and they are therefore suitable for certain surface heat treatment and surfacing applications. These include laser hardening, alloying and cladding. Laser hardening is the most common method of the laser surface heat treatments up till now. One generally uses a shielding gas to protect the metal from oxidizing. Mostly argon or nitrogen is used.

BIP® UHP gases

In a plasma spraying process, inert gases are needed as plasma gas and carrier gas (for the powder). Mostly plasma gases are Argon, Helium, Nitrogen and Hydrogen. One individual gas or mixtures can be used. Since high purities are requested (5.0 grades), BIP® cylinders give you the best results and performances. Only Argon & Nitrogen (pure) are used as carrier gas for the powders, also in minimum 5.0 grades, so best to be used supplied from a BIP® cylinder.

Nitrogen

Nitrogen can be used as an assist gas for laser marking or engraving on any type of material.
