Vertical Kaplan turbines, manufactured in Russia, are
installed in 6 hydroelectric generating units at ‘Djerdap 1’, with
nominal power of 176 MW each. Because of the structural
solution and inability of performing periodic inspections and
state analyses, 40 years long service life of the turbine and upper
ring of guide vane apparatus was predicted. Welded structures of
the turbine cover and upper ring of guide vane apparatus consist
of 4 segments made of steel St 3, in accordance with GOST 380-
94. Flux-cored arc welding was used in order to merge the
segments.
Non-destructive and destructive tests were performed on parent
material and welded joints during the rehabilitation of the
hydroelectric generating set A4, in order to carry out the
condition analysis and assessment of the level and cause of
eventual degradation of structures of the turbine cover and upper
ring of guide vane apparatus at hydro power plant ‘Djerdap 1‘.
In this paper the analyses that refer to dete...rmination of the cause
of lamellar tearing of parent material in the area of welded joints
based on results of magnetic particle testing and ultrasonic
testing are presented.
