E.O. Paton Electric Welding Institute of the NAS of Ukraine 11 Kazymyr Malevych Str., 03150, Kyiv, Ukraine. E-mail: glukhovskyy@gmail.com.comThe question of selection of the methods of repair, control and diagnostics of the technical condition of fillet transitions in the unit of PL15/3251-GK-600 type of the Kyiv HPP by non-destructive testing techniques was considered. Features of instrumental examination of damage and repair of stator columns in the turbine of the hydraulic unit No. 6 of Kyiv HPP for PrJSC «Ukrhydroenergo» «Cascade of Kyiv HPPs and PSPPs» branch are described. The algorithm of examination of the stator columns of the turbine of hydro unit No. 6 of PL15/3251-GK-600 type is presented. Ref. 7, 1 Tabl., Fig. 5.
Keywords: Kyiv HPP, fillet transitions, non-destructive testing, welding, surfacing, repair, visual, capillary, ultrasonic, magnetic method, hydro unit, hydro turbine
