Abstract

This paper presents weld thermal cycle simulation of high strength steel S960QL, and describes influence of cooling time t_8/5 on hardness and impact toughness of weld thermal cycle simulated specimens. Furthermore, it presents analysis of characteristic fractions done by electron scanning microscope which can contribute to determination of welding parameters for S960QL steel.
