At present, pipe fittings have been widely used in various fields. In the process of pipe fitting processing, the fixation of pipe fittings is an extremely important procedure. Usually, welding is used for connection. During welding, the pipe fittings need to be clamped and fixed, so pipe fitting welding clamps are used. Pipe fitting welding clamps perform comprehensive welding by rotating the pipeline.

At the same time, after welding a part, it is convenient to rotate the rotating drum frame by controlling the handle bar to change the position of the weld, so as to facilitate the welding of the unwelded weld, thereby increasing the welding efficiency and reducing the welding difficulty;
