According to the welding quality requirements of long-distance oil and gas pipeline construction, the flash butt welding process of X80 pipeline steel was studied. Through analyzing the chemical composition and mechanical properties, combined with the selected welding process and welding method, the welding was carried out for X80 pipeline steel, and the mechanical properties of its welded joints were tested. The results showed that the flash butt welding performance of X80 steel is very good, and the strength, hardness and low temperature toughness can meet the safety requirement of X80 grade pipeline steel. The welding method and the technological parameters can be used for site welding.
