The robustness of a seam tracking for the automatic welding system is studied. Ac servo motor is used to control the position and velocity of the weld torch. The CCD camera locates ahead of weld torch to preview the weld line, and brings about the inaccuracy on the weld speed. The advanced optimal preview control was used to enhance the tracking performance. The experiment results showed that the tracking performance was improved significantly.
