the first step is as follows: placing the tank body: the two tank bodies are respectively placed on a rotating roller (26) from the left side and the right side of a bearing rack (1), and then the tank bodies are limited through a limiting branched chain (27);

the second step is that: equipment adjustment: the lifting cylinder (21) is started to drive the supporting plate (23) to move upwards through the adjusting frame (22), and the tank body synchronously moves upwards to the lower ends of the welding machine (33) and the grinding branch chain (34) in the upward moving process of the supporting plate (23);

the third step: welding treatment: the rotating motor (25) is started to drive the tank bodies to rotate through the rotating roller (26), the welding machine (33) is started to weld the tank bodies in the two rotating processes, and the welding positions of the tank bodies are polished through the polishing branched chains (34) after the welding is finished;

the fourth step: collecting and treating: the limiting branched chain (27) is reset, and then the welded tank bodies are taken out through the existing equipment to be uniformly stacked.
