Abstract

The presented study involved mathematical modelling of single pass TIG welding of duplex stainless steel S32205. The temperature fields, the fusion zone and HAZ dimension, the cooling rates fields, residual stresses taking into account kinetics of dissolution of austenite during heating and kinetics of precipitation of austenite during cooling were obtained. The comparison analysis of obtained residual stresses without phase transformations
and taking into account phase transformations showed the difference of residual stresses distribution due to different amounts of austenite and ferrite and due to volumetric changes during phase transformations.
