Effect of Heat Input on Weld Microstructure in TIG Welding of Duplex Stainless Steels
Öz
Duplex stainless steels are used in many applications as in oil, chemical, petrochemical, nuclear and marine industries. Welding of duplex stainless steels requires higher attention due to changes in ferrite and austenite phase ratio in weld metal. Higher ferrite or austenite phase ratio induces decreases in mechanical properties and corrosion resistance. In this study, effect of heat input on weld microstructure of duplex stainless steels in TIG welding were investigated. Higher heat input induce austenite structure and grain size changes in weld metal.
