Welding technology in the pipeline production includes a reliable quality control and the control of the weld seams of finished pipes. For the measurement, the ultrasonic transducers of the equipment must precisely follow the weld seam which, however, does not form a perfect straight line due to manufacturing tolerances.
The laser optical seam tracking system developed by iSAM® supports ultrasonic testing systems with a sensor which recognizes the weld reinforcement in the tube surface profile. The seam tracking software guides the probes in an exact track over the weld seam, thus enabling a reliable inspection of the joint.
The 2D laser light-section sensor detects extremely flat seam contours
