Influence of the number of an electron beam runs on the structural phase state of the hardened case on the base of steel P6M5 and steel P6M5 {thorn} 20% WC compound is studied by the methods of optical and raster electronic microscopy, roentgen fluorescent analysis. It is shown that two morphological carbide types are distinguished in the tree-run weld deposition, i.e. elongated along the austenitic granule lines and small equiaxed in volume granules. This gives significant increase in microhardness of the hardened case.
