Welding device for aluminum alloy automobile dashboard bracket

The invention provides a welding device for an aluminum alloy automobile dashboard bracket. The welding device comprises welding tools and welding robots, wherein the welding tools are used for positioning a workpiece to be welded; the welding robots are used for welding a welding seam in the workpiece to be welded; each welding tool comprises a base plate, a plurality of bases which are fixed on the base plate, a positioning mechanism which is fixed on each base, and a cooling mechanism which is matched with each positioning mechanism; each positioning mechanism comprises a positioning block; each positioning block is a hollow copper block in which a cavity and a communication port are formed; each communication port is used for communicating the corresponding cavity and the corresponding cooling mechanism. Therefore, the welding heat dissipation efficiency can be effectively improved, the welding deformation of the aluminum alloy automobile dashboard bracket is reduced, and low-deformation welding control is realized.
