  • Abstract S960 steel is an advanced low carbon and low alloy ultra-high strength steel (with a minimum yield strength of 960 MPa) developed by Tata Steel. At present, there is a scarcity of data for laser welding of such a material. In this study, 8 mm thick hot rolled and quenched S960 high strength low alloy (HSLA) steel plates were welded using a 16 kW fibre laser system. The microstructure, microhardness, and tensile properties were characterised, Charpy impact testing and three-point… CONTINUE READING
