Effects of real welding parameters of high-strength S1100QL steel on hardness and impact energy properties

The research objective was to test the parameters of real welding of the high-strength micro-alloyed S1100QL steel against the hardness and impact energy. The samples were welded at different welding parameters. Results of measuring the HV10 hardness and of experimental Charpy V-notch test performed at different temperatures are presented in tables and diagrams. This paper presents also the welding parameters, which provides a high quality welded joint without cold cracks.
