Simulation of stress distribution in the weld of a dissimilar joint

The article presents the investigations of corrosion properties of welded heterogenous joints. These joints were made of duplex steel of grade 2205-X2CrNiMoCuN22-5-3 (1.4462) and of austenitic steel of grade 316L-X2CrNiMo17-12-2 (1.4404). The joint was manufactured using the welding wire P5 (Avesta, Sweden). The aim of the research was to analyze the matching of a numerical model of the joint with the results obtained in the case of an actual one. The paper presents the modellling process of a joint using an advanced CAD / CAE class system. The advantage of utilization the CAE class system is its ability to investigate the behavior of the whole joint in virtual environment. They also allow conducting numerical experiments taking into consideration the dynamical excitations which affect the operation of the analysed construction. The results show that modeling behavior of heterogenous joints in CAE class system basing on experimentally designated material parameters, allow obtaining results more corresponding to reality.
