Laser and electron-beam welding

Most innovations for industrial application originate in this welding technology. Beam welding benefits from low energy draw and high welding speed, and therefore low distortion and residual stress.

Services

Process variations

  • Laser beam welding with and without welding additives
  • Laser MIG/MAG hybrid welding
  • Laser hardfacing with wire-shaped additives and pulsed solid-state lasers
  • Electron-beam melting [EBM]
    Generative techniques allow the production of complex component bodies and structures. Direct application to freely accessible component areas allows the reliable production of partial surface coatings with high levels of homogeneity.
  • Micro-electron-beam welding [μEB]
    The low heat input in micro-electron-beam welding creates an interesting alternative to soldering or gluing on small parts and micro-components. Eliminating the need for welding additives makes for ideal electrical and thermal conductive properties on the seam when joining two different materials. The electron beam method also provides an efficient way of arranging surfaces to specification using surface hardening, remelting and microstructuring processes.
