Description

Technical Field

[0002] Welding is a common processing method. Welding is also called fusion or melting. It is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many sources of energy for modern welding. When welding the annular pipe, it is generally necessary to do the welding manually, which is inefficient. Therefore, a welding machine specially designed for welding annular welds is selected to replace manual labor.

[0003] For example, an external clamp-type pipe welding machine disclosed in patent CN219151947U achieves annular welding of the pipe without dead angles through the cooperation of a motor, a gear, a gear ring and a welding gun. However, this method requires manual removal and installation and positioning when welding annular welds at multiple different positions, which is very time-consuming and greatly reduces work efficiency. In addition, a lot of time is required to re-calibrate the center of the circle. It cannot be moved directly on the surface of the pipe. If there are protruding bumps on the surface of some pipes, the clamping effect cannot be achieved. Utility Model Content
