Abstract

The microstructural refinement of weld zone in a low carbon steel by thermomechanical processing have been studied. The steel specimens were welded using MAG (Metal Active Gas) tecnique. With the heat of weld zone hot plastic deformation was applied on weld metal by rolling. The thermomechanical processing resulted in a significant grain refinement in both weld metal and heat affected zone. The hardness of weld metal increased. Impact resistance of specimens increased in heat affected zone whereas that of weld metal decreased slightly.

Özet

Bu çalışmada düşük karbonlu bir çelik sacın kaynak bölgesi özelliklerinin geliştirilmesi, kaynak dikişine uygulanan termomekanik işlem yoluyla denenmiştir. Kaynak işleminin devamında, yüksek sıcaklıklardaki kaynak dikişi haddeleme işlemine tabi tutularak sıcak plastik deformasyon sağlanmıştır. Deneysel çalışmalar ile numunelerde, mikroyapı, sertlik ve darbe direnci özellikleri incelenmiştir. Bu incelemeler sonucunda; mikroyapıda tane boyutunda küçülme, kaynak metali sertliğinde artış tespit edilmiştir. Darbe direnci, kaynak metalinde azalırken, ısı tesiri altındaki bölgede artmıştır.
