Acoustical Monitoring of the Stress-Strain State of Welded Connections of a Rotor Frame During Upgrade of the Hydroelectric Unit of the Nizhnekamsk Hydroelectric Power Station

  • Published:
Power Technology and Engineering Aims and scope

Results are presented for research by an acoustic method, of residual stresses and the plastic strains that occurred in a spoke of a rotor frame of the main generator after welding reinforcing plates (additional ribs for rigidity) during upgrade work on the hydroelectric unit of the Nizhnekamsk hydroelectric power station.
