DVS Congress 2021 

“Additive Manufacturing of Refractory Metals”

Presentation on Thursday Sep. 16, 2021 at 02.30 pm (CEST) in German


Additive manufacturing of refractory metals poses special challenges to the surrounding atmosphere, as it must be free of oxygen and nitrogen. The safest method is machining in a vacuum chamber.
As an alternative to electron beam welding, additive machining in a vacuum using a laser is presented.
