On the front of component 306, the top of the inner connecting pipe 306 has a through hole, and the top of the processing table 1 has a rectangular groove. The processing table 1 is equipped with a drive stepper motor. The rotating rod 303 is fixedly connected to the output shaft of the drive stepper motor. By starting the drive stepper motor below, a dual-station rotary welding platform can be equipped to achieve 360-degree rotation and adjust the position of the pressure vessel for processing. The bottom right side of the placement rack 301 has a placement groove, and the air pump 307 is fixedly connected to the inside of the placement groove. The top of the air pump 307 is flush with the bottom of the placement rack 301. The back right side of the placement U-shaped frame 304 has a through groove.
