High-temperature-resistant heat exchanger plate bundle welding equipment

The invention relates to the technical field of heat exchanger welding, in particular to high-temperature-resistant heat exchanger plate bundle welding equipment which comprises a bottom plate, a supporting frame, a positioning unit and a welding unit, the supporting frame is installed on the bottom plate, the positioning unit for positioning is installed on the supporting frame, and the welding unit is further installed on the bottom plate. The four supporting rods in the supporting frame are matched with the positioning units, the heat exchanger plate bundle is limited in the vertical direction, the front-back direction and the left-right direction, the position stability of the plate bundle in the welding process is effectively guaranteed, meanwhile, the plate bundle is switched between the vertical state and the horizontal state through the rotatable supporting frame, and the welding efficiency is improved. The supporting frame is arranged on the upper welding mechanism and the lower welding mechanism so
