Determination of Temperature Gradient in TIG Welding of Duplex Stainless Steel
Öz
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.
