The TH6D-Advanced is our latest development of optical seam tracking sensors for automated laser or arc welding processes. Based on the proven triangulation principle and the latest camera technology, the sensor actively guides the process along the joint or the component edge, thus enabling reliable compensation of component tolerances in real time.
TH6D Advanced
Optical seam tracking for electric arc and laser applications
Function description
The triangulation sensor scans the seam shape along the joint without actually touching it and transmits information including gap dimensions, joint edge offset and positioning of the tool relative to the workpiece surface to the robot controller. Integrated extraneous light filtering ensures smooth operation even in the area close to the process. Efficient signal analysis ensures reliable detection, especially on reflective surfaces.
Areas of application
