[0002] Argon arc welding is a common form of welding; during the welding process of thin-walled workpieces, the shrinkage is difficult to control, and the shrinkage of the thin-walled workpiece after welding is often too large. In the prior art, there is a product composed of a core and a cover; specifically, the cover is connected to the core by argon arc welding. Generally, only the approximate size of the cover before welding is determined based on the drawings using tools such as vernier calipers, and after confirmation of compliance, welding is performed directly. Since the cover is a thin-walled workpiece, its shrinkage cannot be effectively controlled. Therefore, after the cover is welded to the core, the shrinkage of the cover is too large, resulting in the size of the cover being lower than the lower limit, resulting in an unqualified product. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect that when welding the core and the cover, the shrinkage of the cover cannot be effectively controlled because the cover is a thin-walled workpiece, resulting in the size of the cover after welding being lower than the lower limit, resulting in an unqualified product.
