The paper deals with the investigations which consisted in conducting the process of hardfacing of steel sheets from X10CrMoNb9-1 steel. There were two different coatings marked to sheets through the TIG method. The material used on the weld overlay was as follows: W CrMo2Si, W CrMo91. After hardfacing of steel sheets, the examined samples have been cut from the sheets, from which the metallographic samples have been produced. In the paper, there were photographs of microstructures of metallographic samples attached, which were taken during the microscopic observations. The observations using optical microscope Nicon Eclipse MA 200 compared changes in surface microstructure and the effect of TIG welding. The process of hardfacing was conducted on the Electric Invertec V270 device - T pulse.
