| Abstract: | 304H steel was welded by submerged arc welding. The characteristics of submerged arc welding were analyzed and a reasonable welding procedure of submerged arc welding was presented. The qualities of welds were detected, and the microstructure was analyzed, and the mechanical properties were tested. The results show that the welding parameters were reasonable, and any welding flaws were not found, and the quality of welded joints were good. The strength and plasticity of welds were equivalent to the base metal. This method can be adopted in 304H heat resisting austenitic stainless steel welding and the excellent weld can be obtained. |
