The work presents test results of microhardness of surface layer of HS 6-5-2 high-speed steel from areas overlapping remelting. The surface layer of the steel was remelted using the GTAW method. The microhardness was measured using the Vickers method. The work shows that the area, where the heat influence zone of the second remelting overlapping on the first remelting zone is characterizes by the microhardness lower about approx. 200 HV0,065.
