| Abstract: | An investigation in some approaches to digital image technique in measuring and controlling MAG welding arc is conducted in this paper. In this research works, the authors, using the optical welding robot, have controlled arc for improving the welding quality. The control system consists of TV-camera, micro-computer and image memory. The arc length is manipulated quantity in the system, the peak current of welding pulse changes in every period. The result of the study offers a new and feasible method for the automatic MAG welding. |
