摘要 采用有限元分析法对P91/12Cr1MoV异种钢焊接接头残余应力场的分布进行了研究,结果表明:最大残余应力均出现在P91钢侧的内表面。 Both experimental research and finite element method (FEM) were used to investigate the residual stress distribution in multi-pass butt-welded P91/12CrlMoV dissimilar pipe. The result shows that the peak stresses exists on the inner surface of P91 pipe.
