Life optimization of dissimilar metal welds for high temperature components

A new methodology has been developed involving the use of creep and fatigue cross-weld test data for the welded joint's life assessment. The methodology does not involve finite element (FE) simulations of local microstructure of the weld and it is not based on inaccurate generic weld reduction factors. Optimum welds are produced for advanced steels.
