[0002] In the prior art, for example, a utility model with publication number 202222220676.4 discloses a tank body welding device. In order to solve the problem that when welding special-shaped tanks, the special-shaped tank body is placed stationary and the welder needs to move along the weld seam to weld, which not only has low welding efficiency but also uneven weld quality during manual movement, the installation and rotation of the special-shaped tank body can be realized. When the tank body rotates, the welding gun head can float up and down with the rotation of the tank body, so that the welding gun head always maintains the optimal welding distance and angle with the weld seam, thereby improving the welding efficiency and welding quality.
