A coupled approach for the modelling of arc welding processes

Abstract

International audienceA 3D finite element model is presented, addressing some major phenomena arising in arc welding as well as their interaction: heat input, metal deposit, solidification, phase transformations in the solid state and material behavior. As a result of a simulation, the shape of the weld bead, the phase distribution, residual stresses and distortions are obtained. Some application and validation cases are discussed
