Military Engine Component Welding

Engines and transmission components of heavy duty military vehicles operate under some of the most extreme conditions. In this application, three pieces of an engine disc spacer are electron beam welded in two passes at a common joint- the first a deep penetration weld and the second a broad final pass to fully consume the joint and smooth the weld top bead. The part was designed to be completed after the EB welding process requiring no further machining.
