Through Abstract:this the research on paper the introduced debugging method the applicatio­n of laser of flying laser welding flying welding and the system optimizati­on on doors of laser (Body-in-white, welding parameters, BIW). the quality of laser flying welding was certified. The laser welding head communicat­es with the robot through the CAN bus for laser flying welding. Through a large number of experiment­s, relatively stable laser welding parameters were obtained, and it is concluded that the defocusing amount of the laser and the laser power are important parameters that affect the quality of laser welding. Key words: Laser flying welding, Laser pitting, Laser power, Robot
