Researches on Normalizing Heat Treatment Applied to SAW Joints with TWIN-ARC


Article Preview

In this paper is analyzed the effect of normalizing post-weld heat treatment for SAW TWIN-ARC on grain size and aging of the Widmannstätten structure. Tests of elongation and toughness made with welded joints from S355J0 justify heat treatment opportunity and also the structural modification developed in deposited metal and in heat-affected zone.
