Causes of Argon Electric Welding Defects in Large-diameter and High-grade Oil and Gas Pipelines
Large-caliber high-steel grade oil and gas pipeline is a systematic project.In the project construction process,the defects control of argon-electric welding can ensure the stability of pipeline connection,which is of great help to the stable operation of large-caliber high-steel grade oil and gas pipeline system.Therefore,on the basis of analyzing the connotation of argon-arc welding,this paper summarizes the causes of argon-electric welding defects in large-caliber high-steel grade oil and gas pipelines,and puts forward targeted control methods.
