Description

Technical Field

[0001] The utility model relates to the field of tower welding devices, in particular to a novel welding device. Background Art

[0002] As a large-scale equipment commonly used in industry, towers undertake a large part of industrial operations during use. They have complex internal structures and diverse functions. In the early stage of installation, multiple sections of the tower need to be welded, and most of the existing welding is done manually. Manual welding reduces work efficiency to a certain extent and has a certain error in welding accuracy. Therefore, a new welding device is proposed.

[0003] In the existing tower welding, most of the tower sections are placed on a support frame, and then the workers use a handheld welding machine to weld them. When the workers weld manually, there is a certain error in the accuracy of the connection between the two sections, so that leakage may occur when the pressure tower is used later. At the same time, when welding it, the workers need to manually rotate the welded half of the tower so that they can weld the other half, and most of the existing support frames cannot effectively fix towers of different thicknesses. Therefore, technical improvements are urgently needed. Utility Model Content
