Helium for additive manufacturing
Helium is an inert and very light gas. Its chemical and physical properties make it ideal for both PBF and DED 3D printing processes. Since Helium is very rare and expensive, it is mainly used in EBM processes, which are known for their low gas consumption. In the DED process Helium is often used, but mixed with other gases.

Helium for the metal fabrication industry
Like Argon, Helium is an absolutely inert gas that does not react under any circumstances. Thanks to its ionization potential, it transfers more energy, bringing more heat into the welded joint. In addition, the low specific weight of Helium widens the protection cone, which facilitates the cooling of the welded joint.
