Research on the recognition system of visual arc welding

At present, many domestic scholars and research institutions have studied the laser vision welding seam tracking system. By improving the control strategy of the robot and welding seam tracking system, the processing time is optimized and the real-time response of the welding seam tracking system is promoted. However, the practical application of the research results is not yet satisfactory. This paper carries out an experimental study of vision-based arc weld tracking. Its main content contains welding robot kine matics and control systems, weld image processing technology, right angle weld tracking technology, and so on. The research shows that the feature extraction of arc weld based on vision can be completed and arc weld recognition can be realized. It provides some reference for the application of laser vision welding seam tracking systems in industry.
