Reviewing the Influence of Welding Setup on FE-Simulated Welding Residual Stresses

S. Gkatzogiannis, P. Knoedel, T. Ummenhofer

Abstract. Previous and new simulations of welding residual stresses with the finite element method are reviewed in the present study. The influence of modelling mechanical boundary conditions, erroneous prediction of the weld heat source coefficient and the influence of microstructural changes in aluminum welds are investigated. The results are analyzed so that concrete suggestions regarding the investigated factors, acting as guidance to the practitioner, can be presented.
