Description

Technical Field

[0001] The invention belongs to the technical field of automobile parts welding, and more specifically, particularly relates to a implant welding process for automobile body-in-white parts. Background Art

[0002] Automotive body-in-white parts implant welding refers to a method of welding parts using implant welding technology during the manufacturing process of the automotive body-in-white. Implant welding does not require pre-drilling holes in the automotive sheet metal. Instead, one end of the selected stud is placed in the implant welding gun, and the other end is in vertical contact with the surface of the automotive sheet metal. Electricity is applied to strike an arc, and pressure is applied after the contact surface melts to complete the welding.

[0003] The current automotive body-in-white parts implant welding equipment still has the following problems:

[0004] 1. Generally, there is only one welding gun head, which can only weld one stud at a time. It is impossible to weld multiple studs with automobile sheet metal parts at the same time, which reduces the welding efficiency of the studs;

[0005] 2. Usually, there is a lack of welding quality inspection structure, which means that workers need to use sleeves to bend and inspect the welded parts. In addition, the welded parts cannot be inspected in multiple directions, which reduces the accuracy of welding quality inspection.

[0006] 3. It is impossible to automatically mark the studs that fail the welding, which makes it more troublesome for workers to find the welding position later, reducing work efficiency. Summary of the invention
