The automatic welding is widely used for the production of machine and assembly of constructions. It will increase the efficiency of a welding process, productivity and quality of welded joints, it the ability of welding robot,sensors which can monitor a welding process increases. However, there are two problems that the arc welding process is unstable welding and spatters occur in MAG welding and they disturb the vision sensing of welding process. A purpose of this research is construction of a system which is possible to maintain strength of joints in the automatic MAG welding. This system monitors the welding area by CCD camera and the images are processed. Then the system detects welding wire and welding line position, and controls the welding robot to realize the automatic seam-tracking. The new image processing algorithm was constructed to eliminate the bad influence of spatters on a welding image and increase the successful percentage of the welding line detection and the welding wire detection.
