| Abstract: | In-service examinations for welding repaired areas in the coupling of a 600MW steam turbine LP rotor is introduced. Through the seven consecutive in-service examination in the past eight years, the test results demonstrate that the quality and properties of repaired areas can conform to design standards and the rotor can be operated normally. |
