Electron Beam Welding - EBW

keV level

Welding Machine with Electron Beam


Due to its advantages over other welding methods, it is widely used worldwide in the automotive, defense, aviation, and medical sectors.

  • Welding of materials with different melting points

  • Adjustable weld depth

  • Deep and thin welding (0.02 mm bundle diameter)

  • Low heat input

  • Clean welding in a vacuum environment

  • Susceptibility to automation

  • Ability to weld complex geometries

  • High efficiency (single turn - narrow zone (HAZ))

  • High positioning accuracy

  • High welding speed

When we further examine electron beam welding (EBW) and laser welding, both of which have distinct advantages over other welding methods, we can see that EBW uses a well-focused electron beam, while laser welding uses coherent photons. In both methods, the kinetic energy of electrons or photons is converted into heat energy when they collide with the metal surface.

The table below illustrates the pros and cons of both processes. Particularly for applications requiring high weld penetration, EBW is the superior choice.

In summary, EBW is particularly well-suited for applications requiring deep weld penetration, whereas laser welding excels in providing high precision and speed. The choice between the two methods depends on the specific requirements of the welding task.
