Not long ago, after a pre-technological properties, mechanical properties and wire deposited metal and other tests, Baoji Petroleum Steel Pipe Co., Ltd. developed the X80 girth weld wire, the performance can meet the standard requirements, the trial is successful.
Pipeline girth weld wire belonging to the high-end products in the pipeline  Welding Wire consumables. November 5, 2009, the company included in the X80 girth weld wire project West-East Gas Pipeline Project study two major projects, shared R & D task by Baoji Steel Corporation and the China Petroleum Pipeline Bureau.
 The test wire deposited metal test is extremely difficult. Gas shielded wire energy is small, the depth of weld penetration, and multi-layer multi-pass welding, filling nearly 70 in the narrow groove weld, it is easy to produce welding defects. As long as there is a weld problems, have all polished off. Sometimes continuous welding for a week, even a qualified deposited metal test panels are not completed. The group members all day long soak in the laboratory to look into the problem, find a cause, and finally the wire mechanical properties meet the standard requirements.
 To wire process performance test, the project team members went twice the Langfang Pipeline Bureau, Institute of Science and Technology, after nearly a month of debugging process, the successful Welding Electrode of qualified weld. Wire test report developed by Baoji Steel X80 girth weld wire excellent welding performance, arc stability, all-position operating performance and weld good, good girth weld appearance, the film qualified, to meet Q/SY-GJX0110 West second-tier line welding of pipeline engineering technical specifications.
Pipeline girth weld wire belonging to the species of high value-added consumables, pipeline construction site, basically a few companies of foreign products, and wire prices higher. The localization of the X80 ring weld wire will break the monopoly of foreign enterprises, to meet the building needs of the domestic high-grade steel pipe.
