    Abstract

    The members of the NeT network have undertaken parallel round-robin activities measuring and predicting transient temperatures, fusion boundary development, weld residual stresses and structural distortions in a benchmark specimen manufactured from AISI 316L(N) plate with a central finite length slot filled with three superimposed TIG weld beads. This is a strongly three-dimensional configuration with many of the characteristics of a repair weld. The round robin finite element predictions of residual stresses and distortions are compared with an extensive database of residual stress and distortion measurements made using diverse techniques on multiple TG4 specimens. It is found that high solution accuracies can be achieved.
