Problems solved by technology

That is to say, even if the structural parts can be automatically welded by the welding robot, the finished welded structural parts need to be removed from the welding platform, and after aging treatment, they should be placed on the inspection platform for weld inspection. There is a problem of deviation between the positioning reference of the weld inspection and the positioning reference during the welding process, and the weld inspection of the structural parts cannot realize the online inspection with the same positioning reference on the welding platform
In addition, due to the unavoidable welding deformation, the tolerance range of welded parts is generally on the rough millimeter level. The welded finished size of the welded structural parts usually deviates from the standard structural part design size, which results in the standard structural part design size. There are deviations between the weld position size and path length of the generated structural weld modeling model and the weld position and path length of the actual welded product of the structural part. Therefore, it is difficult to automate the weld detection of structural parts, and inspection personnel are usually used Manual testing is carried out by testing instruments. However, manual testing not only has the influence of human factors such as the sense of responsibility and emotion of the inspectors on the inspection progress, but also requires high testing skills and experience for the inspectors.
