In many applications that use high strength steels, structural integrity depends greatly on weld quality. Imperfections and the bead geometry are influencing factors mechanical properties of welded joints but, especially in fatigue strength, they cause a great decrease. The proper knowledge these two is important from nominal stress approach to fracture mechanics approaches. Studies concerning ...

This article provides an overview of the influence welding parameters and filler material on changes in heat-affected zone (HAZ) thermo-mechanically controlled processed (TMCP) steel welded joints. The research focused evaluating effect heat input cooling rate width soft zone, which significantly affects mechanical properties negative is more pronounced as thickness decreases. Therefore, object...
