N2 - P91/12Cr1MoV dissimilar steel welded joints are widely used in the superheater and reheater tubes at elevated temperature. Therefore, it is of great significance to predict the creep rupture life of the P91/12Cr1MoV dissimilar joint for safe operation. In this paper, Omega method was used to predict the creep curve of T91/12Cr1MoV dissimilar joint based on the creep test results. The predicted life was found to be invariably above the experimental result, and was in close relationship with the Omega value. A larger value can be obtained from lower stress, and the results obtained from lower stress are more close to the experimental ones.
