Description

Technical Field

[0002] Automotive sheet metal parts refer to the metal parts that make up the outer shell of the car body. They are usually made of steel plates through stamping, welding, bending and other processes. They play a role in protecting drivers and passengers, improving the structural strength of the vehicle, and shaping the appearance of the vehicle. Automotive sheet metal parts have different shapes depending on their use. When welding arc-shaped automotive sheet metal parts, a clamping structure is required to clamp and fix them. A simple clamping structure may cause the arc-shaped automotive sheet metal parts to shift during welding, resulting in the shift of its welding track, making the appearance after welding less beautiful.

[0003] Secondly, the welding offset of arc-shaped automobile sheet metal parts may cause some positions that need to be welded to be incompletely welded, resulting in some weld leaks, which then require rework and welding, reducing welding efficiency and increasing welding costs. If the welding quality does not meet the standards and is not discovered during quality inspection, greater quality or safety problems may occur in future use.
