Abstract

This paper introduces the welding performance of Super304H steel. The welding process tests of Super304H steel including room tensile tests, bending tests and hardness tests, were carried out in ultra-supercritical boiler, with the use of pulsed arc welding power and ER304HCu welding wire. The results show that the welded joints of Super304H steel have good performance, normal microstructure, and its mechanical properties can meet the specification requirements. The welding process designed according to the testing results can be used for engineering installation and maintenance.
