| Abstract: | Aim at the welding problems of T91 and 12Cr1MoV dissimilar steel occurred in thermal generator unit, which caused by different working temperature in dissimilar steel various parts, the weldability of SA213-T91 and 12Cr1MoV dissimilar steel was analyzed, and reasonable welding process was established. Through strict control of preheating temperature, interlayer-temperature, post-welding heat treatment parameters and other measures, the welding test was completed. This welding process was applied to practice, and achieved good results. The test result showed that the welding process parameters and welding method are reasonable. |
