Abstract

This paper presents accelerated weldability investigation after weld thermal cycle simulation of TStE 420 steel. The method enables single cycle or multiple cycle thermal simulation of base material specimens and obtaining any point in the heat-affected zone (HAZ) of a welded joint. After weld thermal simulation, an investigation of mechanical properties on treated specimens (hardness, toughness…) is foreseen, based on which it is possible to determine weak points in HAZ of a welded joint and inference regarding to base metal weldability.
