A workshop on the Weld Repair of High- and Intermediate-Pressure Turbine Rotors for Life Extension was conducted on December 1--2, 1987 at Hyatt Rickeys Hotel in Palo Alto, California. The workshop was sponsored by the Electric Power Research Institute (EPRI). Approximately 75 individuals participated in the workshop including domestic and foreign utilities, equipment vendors, contractors, and consultants. The objectives of the workshop were to provide utilities with an opportunity to exchange case histories, to allow manufacturers and consultants the opportunity to present new technologies, and to identify needed research on weld repair issues. To meet these objectives, papers were provided on the following topics: utility experience, weld repair techniques, materials testing, and overview - survey of the state-of-the-art. Each topic was discussed in a separate workshop session. The papers were followed by an extensive discussion period that produced significant interaction between the participants. All papers presented at the workshop are included in these proceedings and each section of the proceedings is followed by an edited transcription of the discussion period. 35 refs., 33 figs., 17 tabs.
