| Abstract: | P91/P92 new martensitic heat-resistant steel have strict requirement on technology in welding process. If welding parameters and welding technology measure can not be controlled properly, it is easy to produce welding defects. Understanding defect characteristics and generation mechanism of the new martensitic steel P91/P92 for different welding methods and welding technology is very important to the quality inspection of the welded joint. In this paper, according to various welding defects generated in the practical construction procedure, the defect characteristics, generation mechanism and the preventive measures were described. |
