Abstract
Welding-induced residual stresses and distortion can play a very important role in the reliable design of welded joints and welded structures. In fusion welding, a weldment is locally heated by the welding heat source. Due to the non-uniform temperature distribution during the thermal cycle, incompatible strains lead to thermal stresses. These incompatible strains due to dimensional changes associated with solidification of the weld mental (WM), metallurgical transformations, and plastic deformation, are the sources of residual stresses and distortion.However, the welding process itself is a very complex phenomenon, which has not been fully understood, so that the distribution and magnitude of residual stress is not readily available from the literature. It is therefore, necessary to develop a model for the welding process, which would produces not only qualitative but also quantitative information on residual stresses.In this work, a finite element simulation of the welding process yielding the welding-induced residual stresses in a butt-welded plate is presented. The model was validated by compression of its predictions with numerical simulations. Parametric studies were carried out on the validated model to assess the effects of the amount of heat input, the yield strength of the material as well as the temperature-dependence of material properties on the final residual stresses. Based on these studies, a simplified modeling procedure of reasonable accuracy was proposed
