Robotic Laser Welding

 Standard Optics – all robot motion, fixed beam

  •  Typical for butt joint and overlap welding
  •  Beam spinning or Trepanning optics for stir welding process*

 2D/3D Scanner head – Remote Laser Welding (RLW)

  •  Gap Bridging and seam widening
  •  *Stir welding – assist with material prone to hot-cracking and porosity (copper, aluminum)

Features Available

  • Weld monitoring and analysis for process verification
  • Seam Tracking
  • Auto Focus
  • Gap measuring
  • Depth validation
  • Joint position tracking
  • Real-time process monitoring
  • Data tracking and storage
