Electron-beam welding plant “ELU-PM” is made for welding and heat treatment of cylindrical and conical workpieces made of stainless steel and heat-resistant superalloys, by two electron-beam guns:
- With a vertical direction of the beam (top to bottom) when welding circular, circumferential and longitudinal seams.
- With horizontal beam direction (across chamber) for welding circumferential joints.
