Abstract
It is necessary to develop new production and new processing strategies in order to make lightweight construction adapted successfully. In this paper, the fundamental mechanical properties of hull steel CCS-B sandwich plane laser-welded joint and base metals were presented. For the flat grooved specimens with various radiuses, with increasing of initial stress triaxiality, the relationships between the initial stress triaxiality and the equivalent strain to fracture are fitted using an exponential function. The microstructures, tensile properties and impact toughness values of base metals and weld metals at various testing temperature are compared and analyzed.
