Technical Field

[0001] The utility model relates to the technical field of fuel pipelines, in particular to a positioning welding mechanism for fuel pipelines. Background Art

[0002] A fuel pipeline is a pipeline that can transport crude oil or petroleum products. Due to the airtightness requirements of transportation, the pipeline cannot leak during transportation. Among the existing fuel pipeline connection methods, welding and flange sealing connections are mostly used. The transportation efficiency of the fuel pipeline has been greatly improved compared to the efficiency of vehicle transportation.

[0003] In the process of existing fuel pipeline production and laying, it is necessary to consider the laying position and laying length of the pipeline. The existing pipeline connection is mostly flange sealing connection or welding operation. In the conventional welding operation process, it is easy to cause the pipeline welding to be misaligned due to a slight offset in the position of the two pipelines. In addition, during welding, due to the circular characteristics of the pipeline, it is difficult for personnel to weld.
