In heavy fabrication, cutting and bending tolerances never perfectly match the theoretical CAD model. On thick plates and long seams, thermal expansion reshapes the workpiece during welding.
Laser seam tracking projects a triangulation-based laser line ahead of the torch. The optical sensor continuously computes the joint cross-section, root gap and misalignment angle.
The resulting coordinate corrections stream to the robot controller in real time. The robot follows the seam live while adapting parameters to the measured gap.
