Description

Technical Field

[0001] The utility model belongs to the technical field of stainless steel storage tank production equipment, and particularly relates to a stainless steel storage tank welding device. Background Art

[0002] There are two types of storage tanks, namely vertical stainless steel tanks and horizontal stainless steel tanks. Steel plates are rolled into cylindrical shapes and welded into cylindrical shells, and then the steel plates are cut and extruded into disc shapes, and then the disc shapes are welded into the top and bottom to form a storage tank.

[0003] When welding the tank top or tank bottom, the welding points surround the cylindrical shell by 360 degrees. During the welding process, the staff needs to rotate around the shell, so it is necessary to fiddle with and adjust the wires on the ground, thus causing the problem that welding stainless steel storage tanks is rather troublesome.

[0004] Therefore, we propose a stainless steel storage tank welding device to solve the above problems. Content of the Utility Model
