Vacuum Laser Welding Systems

PTR-Precision Technologies, a leading manufacturer of electron beam welding systems, has combined recent advantages in fiber delivered lasers with our extensive knowledge of vacuum processing to create LASVAC: Laser Welding in Vacuum. Compared with conventional laser welding, laser welding in vacuum offers:


  • Higher Aspect Ratio Welds
  • Deeper Penetration (~2X)
  • Less Heat Input
  • More Consistent Results
  • Less Weld Spatter
  • Cleaner Parts After Welding

LASVAC Welding System


These images show a comparison of a laser generated plasma plume at varying pressures. A reduced pressure laser welding environment has significant positive influences on process parameters and weld characteristics. At a given power level, increased weld depths (~2X) can be achieved.





LASVAC vacuum laser welding technology provides the cleanest laser welding environment possible, eliminates the need for virtually all cover gases and can integrate directly with existing laser welding lines. Weld spatter and post weld part clean-up are either greatly reduced or completely eliminated.
