Abstract

Dissimilar metal welding (DMW) introduces residual stresses within a component which are influenced by a number of factors. These include manufacturing stresses in the base material, overall geometry, thermal and mechanical properties of the components and finally the welding parameters employed. Recently it has been found that Inconel alloy 182, which has been used in DMW is susceptible to stress corrosion cracking. Extensive investigations into structural integrity have been performed. This paper discusses the outcomes of a programme of measurements made using the Deep-Hole Drilling (DHD) technique on benchmark laboratory and full-scale preservice components containing DMWs, DMW repairs, stainless steel welds (SSW) and Optimized Weld Overlays (OWOL). The studies were conducted by comparing the results of different laboratory measurements and analytical models.
