Electron beam welding applications

Electron beam welding process is done under the vacuum, the welds are clean and free from oxides and nitrides so this process posses various application.

Application of electron beam welding : 

  • High depth-to-width ratio eliminates multiple-pass welds. Penetration is 0.001 to 2 inches.
  • Welds up to 95% of the strength of the base material.
  • By using this process welds in close proximity to heat-sensitive components because of minimizes shrinkage and distortion.
  • Precise control and repeatability at speeds from 1 to 200 inches per minute.
  • This process permits welding of refractory and dissimilar metals not weldable with another conventional welding process.
  • Electron beam welding is ideal for sealing of pre-evacuated housings and electrical components.
  • In power generation, vacuum system and medical field. 
  • In aerospace sensors like jet engine components, transmission components, parts of structures.
  • In space sensors like titanium tanks.
  • In automotive industries gears, transmission part, parts of a turbocharger.
  • Welding of metals with dissimilar melting points for example - steel to nickel alloys, copper to nickel alloys, copper to steel, tantalum to tungsten.
