摘要
The service life of a high temperature plant is frequently limited by creep damage in welded joints. The factors affecting weld performance under creep conditions are poorly understood. This paper presents the results of modelling of creep in some 240 different girth welds. The effects of weld angle, weld metal and heat affected zone material properties, heat affected zone width, and added axial loading were noted on the stress response of the models. A significant increase in stresses was seen with added axial loadings. The results include a number of results which allow us to specify construction and operation parameters, to assess which welds are at risk in service, and to define inspection or replacement strategies.
