WELDABILITY INVESTIGATION ON REAL WELDED PLATES OF FINE-GRAINED HIGH-STRENGTH STEEL S960QL.

The paper presents results of impact energy effects on real welded specimens of fine-grained high-strength S960QL steel, and elaborates the dependence of real welded specimen hardness on heat input. Results are obtained through measuring of hardness HV 10 and by experimental Charpy V-notch test. V-notch on test tubes was moved for 0,5 mm from the fusion line in the heat affected zone.
