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.

Özet

Çift fazlı paslanmaz çeliklerin kaynağında, yüksek ısı girdisine bağlı olarak ferrit/östenit faz dengesi değişmekte ve çeşitli intermetalik fazlar oluşabilmektedir. Özellikle, ısı etkisi altındaki bölge (IEAB) ferrit/östenit faz dengesinin değişimine ve intermetalik faz oluşumuna karşı oldukça hassastır. Bu nedenle kaynak işlemi sırasında özellikle IEAB’de oluşan sıcaklık eğimcesinin belirlenmesi oldukça önemlidir. Bu çalışmada, IEAB’deki sıcaklık dağılımının belirlenmesi için ANSYS yazılımı kullanılmıştır. IEAB’de oluşan en yüksek sıcaklık değeri belirlenmiş, analizler sonucu elde edilen soğuma hızı değerleri, teorik olarak hesaplanan değerler ile karşılaştırılmıştır.
