heal.abstract A three-dimensional (3D) numerical simulation model of the multi-pass butt welding of AISI 316L austenitic stainless steel plates is developed with the use of finite element analysis, based on the ANSYS® software. The uncoupled thermo-mechanical analysis of the model performed aims at reliably predicting the residual stresses field and deformation due to welding. All the major physical phenomena associated with the welding process, such as heat conduction and convection, heat radiation, and convection heat losses are taken into account in the model development. The thermal and mechanical material properties are introduced as temperature dependent functions, due to the high temperatures of the weld pool and the high temperature gradients that are present during the welding process. During austenitic stainless steel welding any phase changes occurring are considered negligible and are thus ignored in the model. The model's accuracy is evaluated by comparing it with the experimental results from a multi-pass 316L austenitic stainless steel butt welded joint. © 2009 Taylor & Francis Group, London. en
