Fully automated welding places great demands on quality and precision. Consequently, the correct position of the respective seam must be reliably detected before the welding process is started in the robot cell. Welding systems are equipped with innovative weCat3D 2D/3D profile sensors for the purpose of weld seam tracking.

  • Easy integration
  • High profile quality for high process reliability
  • Integrated cooling/rinsing
  • Compact and robust format (IP67)
  • Optional integrated data evaluation for tracking point determination
