Description

Technical Field

[0001] The utility model belongs to the technical field of projection welding equipment, in particular to a compatible projection welding tool. Background Art

[0002] Projection welding is a type of resistance welding process. Projection welding can achieve simultaneous multi-point welding and welding of metal parts with large differences in welding thickness. In order to ensure the position accuracy of the projection weld nut and the consistency of the projection welding quality, as well as to ensure the safety of the operator, projection welding tooling is required for positioning welding.

[0003] In the existing welding process, when welding projection welding parts, most of the time, only one projection welding nut can be welded first, and then the projection welding part is removed, and the position is readjusted before projection welding the other projection welding nut. This not only affects the projection welding efficiency, but also causes inaccurate positioning of the projection welding parts during the projection welding process, resulting in poor projection welding efficiency. Therefore, it is necessary to solve the problem of compatibility of projection welding tooling. Utility Model Content
