Abstract: This paper deals with a seam tracking system of welding of Tailored Weld Blanks based on active lasertriangulation. The system consists of DSP based vision camera and stripe-type laser diode. The total system is assembled into a compact module which can be attached ahead of welding torch and it has high dynamic performance in guiding the robot arm welder accurately over the seam. its structure, basic principle of this system and the main function are introduced. The images taken by the camera are analyzed usin…
