The results of the research of the laser remelting of the steel surface 30Mn4B with the metalic boron layer on structures and microhardness changes have been presented in the paper. The surface layer of the tested steel was remelted with the laser of a continuos work. The power density was from 1,7∙10⁴ to 3,0∙10⁴W/cm². The metallographic tests were conducted (LM and SEM) of the received structure and the microhardness measurements of the layers rising during the machining. The relation between the power density of the laser beam falling on a material, and a geometry of the remelted layers and their microhardness.
