[0002] Sheet metal parts are products processed by sheet metal technology. We cannot live without sheet metal parts in our lives. Sheet metal parts are made by filament power winding, laser cutting, precision welding, roll forming, metal sheet bending, die forging, and water jet cutting. Sheet metal parts have the characteristics of light weight, high strength, low cost, and good performance in large-scale mass production. There are many processing procedures for sheet metal parts, and one of the processing procedures is to weld the seams of sheet metal parts.

[0003] At present, commonly used welding devices use air cooling to cool and dissipate the heat of the welded sheet metal parts when welding the sheet metal parts, and usually use natural cooling after welding is completed, which leads to slow cooling speed of the sheet metal parts and reduces the processing efficiency. For this reason, the present invention provides a sheet metal butt laser welding cooling device that can both follow the laser welding head to air cool the welded sheet metal and water cool the welded sheet metal parts after welding is completed. Summary of the invention
