ELECTRON BEAM WELDING

Electron Beam Welding (EBW) is a high energy density welding process, which generally takes place under vacuum and without filler material. It consists in bombing the parts with high speed electrons; the impact producing a very intense local heating which melts the metal immediately. The relative displacement between the beam and the parts produces a very high quality weld.

Application field and advantages

  • Many possible configurations
  • Very large welding capacities: from very thin to thick thicknesses in 1 single pass.
  • Weldability: all the metal can be fused. For example: steels, stainless steel, copper, aluminum, nickel, cobalt, molybdenum, tantalum, tungsten, titanium and most of their alloys. Heterogeneous welds are possible
  • Reliable, fast and reproducible process
  • Small deformation and thin heat affected zone
  • No protection gas needed (vacuum = best protection)
