[0002] With the rapid development of modern industrial technology, the demand for liquid storage tanks, as important equipment for storing and transporting various liquids, is increasing. In the manufacturing process of liquid storage tanks, welding technology is a crucial link, which directly affects the sealing, strength and service life of the tank. Therefore, efficient and stable arc welding equipment plays an indispensable role in the production of liquid storage tanks.

[0003] Arc welding technology uses the heat generated by the electric arc to melt the metal at the joint of the workpieces, thereby achieving the connection between the workpieces. This welding method has the advantages of high weld quality, high welding efficiency, and flexible operation, and is widely used in the welding of various metal materials. In the welding of the liquid storage tank, arc welding technology also plays an important role.

[0004] When performing arc welding on tanks such as liquid storage tanks, it is generally adopted to drive the liquid storage tank body and the tank cover to rotate synchronously so that the contact surface of the liquid storage tank body and the tank cover evenly passes through the working area of ​​the welder. This method ensures the uniformity and continuity of the weld. However, this method of welding along the contact surface of the liquid storage tank body and the tank cover cannot be flexibly adjusted according to the actual situation during the welding process due to the fixed welding trajectory, which easily leads to insufficient welding in certain specific areas, affecting the uniformity of the weld and reducing the welding quality of the device.
