Robot welding applications have a wide market. As the third major processing method in mechanical manufacturing, 45% of the steel output needs to be manufactured into products by welding. There are a wide variety of welded products. In general industrial products, the welded products are relatively large in size, mostly long straight welds and closed circular welds. Therefore, welding industrial robots need to have better position reachability and posture reachability. In addition, it is also difficult to achieve good repeatability and consistency in terms of dimensional position accuracy and groove alignment quality of welded components.
