The examination of the structure, hardness and abrasion resistance of surface layer of high speed steel: HS 2-10-1-8, HS 6-5-2 and HS 10-2-5-8 after arc plasma and laser welding are presented in the paper. They are compared with the properties obtained after conventional hardening. Diode laser of continuous operation and GTAW (Gas Tungsten Arc Welding) method were used. As a result of concentrated energy beam treatment applied to a steels surface layer, the structures characteristic of rapid solidification / crystallization process were obtained. The treatment of the steel by arc plasma electric with a single remelted track about 7 mm width does not lead to growth of the mechanical and tribological properties of high speed steels. The growth of microhardness as well as low the coefficient Archard of the high speed steel after remelting on the surface single track about 6 mm width by diode laser using can be obtained.
