    摘要: A process is disclosed for repairing leaks in turbine generators that have water cooled stator coils with hollow conductor strands. Such generators have a tendency to leak where the stator coil joins a header. Once a leak is detected the repair is accomplished by following the steps off the invention. First, the header is cut into an outboard section, and into an inboard section that remains attached to the conductor strands. Second, the exposed lead ends of the conductor strands and the attached inboard section are cleaned to remove oxidation. Third, a water-tight braze seal is applied over the lead ends of the conductor strands. And finally, the stator coil and the inboard section are joined to a new outboard section.
