The utility model can reduce the system temperature of the positioning device and ensure reliable and stable positioning; its scheme can quickly position the welding machine and the welded pipe fitting, can realize accurate concentric positioning of the welding gun with the welded pipe fitting, and ensure that the radial distance between the welding gun and the pipe fitting remains unchanged when the welding gun rotates around the welded pipe fitting for rotation welding, so as to ensure the welding quality.

[0003] Then in the actual welding process, after the pipe to be processed is positioned by the fixing device, the position of the welding head needs to be adjusted according to the pipe diameter of different pipes. The existing technology is generally controlled by a vertical lifting control mechanism, which is generally positioned according to the position where the pipe to be processed needs to be welded, that is, the welding position is aligned with the welding head. If welding is completed, other positions need to be welded. The existing welding tooling lacks a suitable auxiliary mechanism to control its movement. Generally, the pipe fittings are disassembled and repositioned, which is troublesome to operate. Furthermore, when adjusting the position of the welding head, the welding head is generally contacted with the processing position to be welded. During the welding process, if there are impurities or adhered particles on the outer wall of the rotating pipe fitting, it may cause extrusion damage to the welding head or insufficient welding at certain positions, affecting its welding process quality.
