Description

technical field [0001] The invention relates to a welding tracking device for a pipeline surfacing system, belonging to the technical field of natural gas pipeline welding. Background technique [0002] Since the oil to be transported contains sulfur elements and acidic substances, in order to prevent the oil pipeline from being corroded and damaged and improve the service life of the pipeline, the composite oil pipeline is selected. The lining pipe material of the composite oil pipeline is 316L stainless steel to ensure that the oil pipeline does not corrode and rust; the material of the outer base pipe is carbon steel to ensure that the oil pipeline has good strength and is not easy to be damaged. [0003] During the transportation of oil products, it is necessary to splice oil pipelines of 10 to 20 meters long to realize long-distance transportation of oil products. There are three main connection methods for pipelines: threaded, welded and flanged. Because welding has ...

AI Technical Summary

Problems solved by technology

[0005] In the actual production process of the oil pipeline, the transverse section of the pipeline cannot be guaranteed to be a standard circle, and the centerline of the pipeline cannot be guaranteed to be a straight line, and the pipeline has a certain deflection in the length direction

During the surfacing welding process on the inner wall of the oil pipeline, if the welding torch is fixed, the welding position will change up and down as the pipeline rotates, the distance between the welding torch and the pipeline will change, and the length of the arc will change, resulting in unstable welding process. The forming condition of the weld seam is poor, and the welding quality cannot be guaranteed
