Sheet metal parts are lighter in weight, easier to machine, have better consistency, and are cheaper in price. As a widely used metal part at present, the body of the sheet metal is relatively thin and lacks hardness. When welding, if it is not fixed well, it is very easy to deform due to heat, resulting in damage to the outer shape during the processing. Therefore, for a sheet metal welding device, the fixation of the sheet metal is a crucial link. For different sheet metal parts, specific parts need to be clamped according to different structures during welding to ensure that the sheet metal maintains a good designed outer shape after welding. The existing sheet metal welding is inconvenient to fix, resulting in large welding errors, and the fixing speed is slow and the efficiency is low during the clamping process.
