Abstract
In welding of DSS, austenite/ferrite phase ratio can vary and various intermetallic phases may occur in weld metal due to excessive heat input. Especially, HAZ is very sensitive against the variation of austenite/ferrite phase ratio and formation of intermetallic phases. Thus, determining the temperature gradient in welding is very crucial. In this study ANSYS workbench was used for defining the temperature gradient in HAZ. The peak temperature in HAZ generated during the welding was determined and also, cooling rates of the analysis were compared with theoretical cooling rate values.
