Reliable Positioning of Welding Seams in Welding Systems

Reliable Positioning of Welding Seams in Welding Systems

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 welding seam tracking.

Outstanding Performance and Efficiency: The weCat3D Series for Welding Systems

Fillet weld | V seam | HV seam | Y seam | HY seam | Sealing bead 

The compact weCat3D profile sensor is mounted directly to the welding torch. The welding system moves along the entire contour of the object during the process. The measured data of the sensor recorded in this way is continuously sent to the controller via the created program in the wenglor uniVision software, which runs on the BB1C001 analysis module. This happens at the same time as the welding process – the welding seam inspection then follows.
