| Abstract: | Taking X80 pipeline steel used in West to East Gas Pipeline II Project as the research object, the X80 pipeline steel was welded under the selected welding parameters, and the mechanical properties of the joint were tested using STF root welding and filling covered surface conducted by PAW2000 welding machine. The results of test show that the welding performance for use of X80 pipeline steel is very good, and each performance index can meet Q/SY GJX 0110-2007. It has been successfully used in west to east gas pipeline II project and has got good welding quality. |
