Control method of visual welding process system

Abstract

The invention discloses a control method of a visual welding process system. The control method comprises a visual guidance welding seam locating technology, a redundant laser positioning detection technology, a welding seam tracking and laser deviation correction technology, a robot autonomous motion planning technology, an autonomous adaptive welding technology and a welding seam defect identification technology. A visual guidance welding seam position searching technology comprises the steps of visual image collection and preprocessing, welding seam recognition, key point position coordinate calculation, welding seam teaching information and robot automatic path planning, and welding seam teaching information is formed by conducting image processing on a welding seam image of a workpiece to be welded and calculating welding seam starting and ending point position coordinates. In order to solve the problems of multi-layer multi-pass welding deviation accumulation and the like, the non-standard part welding seam locating technology based on machine vision guidance is researched, intelligent workpiece welding seam recognition and locating are achieved, and a robot is guided to conduct intelligent welding operation.
