The main function of this system is to automatically track and correct the welding welds, to solve the welding quality problems caused by the high labor cost and the visual fatigue during manual operation. It includes TIG weld tracking and laser seam tracking. The system adopts advanced intelligent vision technology and integrates optical and electromechanical technology. At present, no similar products have been found in China. The system captures the welding video of the weld and the tungsten rod by the visual acquisition system, and then uses the visual technique to calculate the offset of the tungsten rod, thereby controlling the electromechanical device to correct the position of the tungsten rod in real time, so as to achieve the purpose of automatic tracking of the welding, thereby achieving unattended operation. High quality welding requirements.
