Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and 2, a positioning device for welding a pipeline includes:

the base 1 is fixedly connected with the external frame;

the pipeline clamping device is arranged above the base 1 and used for keeping the position of the pipeline 5 unchanged;

the pipe clamp is in sliding fit with the base 1.

The working principle is as follows: as shown in fig. 2, in the area to be welded in the gap between the two pipes 5, the pipe clamping device can ensure that the positions of the two pipes 5 are unchanged, and the base 1 is fixedly connected with the external frame, so that the positions of the two pipes 5 to be welded are ensured to be unchanged, and then the two pipes 5 are welded; utilize pipeline clamping device to fix two pipelines 5 that need the welding and adjust well, guaranteed that two pipelines 5's position is unchangeable, then weld, need not artifically adjust well the pipeline, reduce operating personnel intensity of labour, two pipelines 5's axiality is good, and the seepage is difficult to appear in follow-up application.
