【Abstract】 Authors developed a new type of weaving arc sensor and automatic seam-tracking system.The microcomputer controller was used in this system. It was succesfully applied to the butt welding of circumferential of pressure vessel using pulse MAG welding.The practices prove that the higher seamtracking accuracy and quality weld can be obtained by using this control system.更多还原
