Principle Plastic Welding

Beam transmission welding process

  • Often used common welding process
  • Laser transmits through the upper part
  • Absorbtion in the lower part
  • Transformation of the laser energy into heat energy; the material melts onto the part
  • Work pieces are pressed together with a continuous clamping force
  • Rapid strength after solidification
  • Two established processes: contour welding and quasi-simultaneous welding


  • High welding seam quality
  • No fluff
  • Permanently sealed and invisible connections
  • Touchless, therefore no tool wear
  • High reproducibility
  • Gap bridging with high speed deflection systems (scanners)
  • Alternatively handling via CNC or robot systems
  • Availability 99.5%
