A limiting column is fixedly connected to one side of the bottom plate 12, and the other end of the limiting column is slidably connected to the inside of the side plate 8. A supporting leg 2 is fixedly connected to the bottom of the workbench 1, and an anti-slip pattern is provided on the bottom of the supporting leg 2. During use, the two tank bodies to be welded are respectively placed inside the two transmission plates 7, and the two No. 3 motors 19 are started, so that the two limiting plates 21 both have threaded movement to preliminarily limit the internal tank body. The No. 2 motor 11 rotates the transmission screw 10, and the bottom plate 12 moves due to the movement of the transmission screw 10, so as to limit the other end of the tank body, thereby ensuring the stability of the tank body. The No. 1 motor 3 is started, so that the No. 1 gear 4 drives the No. 2 gear 6 to rotate, and the No. 2 gear 6 drives the No. 1 double-thread screw 5 to rotate, so that the two transmission plates 7 outside the No. 1 double-thread screw 5 are close to each other, so that the welding parts of the two tank bodies are close to contact, and then the welding components inside the sootblower welding box 22 are taken out to weld the tank body.

During the welding process, the vacuum pump 15 can be started to allow the vacuum pump 15 to extract the exhaust gas generated during welding through the suction hopper 14, and discharge it into the gas collecting box 16 through the conduit. Since an activated carbon plate is provided inside the filter plate 17, when the gas accumulates, it will continuously precipitate through the activated carbon plate, so that the gas can be filtered and discharged, thereby improving the environmental protection performance of the welding equipment.
