|The research status of seam tracking for welding robot
Lü Jian， Lü Xueqin
|Various kinds of sensors and intelligent control methods were applicated in the welding robot, it has greatly promoted the application of the robot in welding seam tracking. And it has not only improved the precision of seam tracking,but also improved the welding efficiency and welding quality. The structure of the seam tracking system was described, and the sensors used in the seam tracking process and its working principle were also described. The image processing technologies, such as pre-processing, image segmentation,edge detection,feature extraction and so on,were analyzed.Finally,the intelligent control and the seam tracking method with different weld lines was also summarized.
