Abstract

Detailed analysis of dissimilar metal welds (DMWs) is difficult and the accuracy of the results is often limited by the availability of materials data and knowledge of operating conditions. There are few design or assessment procedures that explicitly take account of the presence of DMWs under high temperature creep and fatigue conditions. One that does is the UK R5 procedure, which provides a simplified assessment approach based on laboratory testing and stress analysis supported by service experience. This paper briefly summarises the R5 approach. Then, more recent work on performance of DMWs operating at high temperature and issues for development of analysis methods is discussed.
