[0003] As a common means of transportation, vehicles are composed of many parts. Welding is usually required in the production process of vehicle parts. Smaller parts are assembled into a larger whole through welding. However, there are many special-shaped parts in automotive parts. Due to their unique shape, special-shaped parts are easy to move when placed, thus affecting welding. Summary of the invention
