The runner body is one of the typical overcurrent parts of a hydroelectric unit. In the long-term water erosion process, it is easy to generate a large number of erosion pits on the side of the flow stop, which affects the normal working conditions.


Our company uses laser cladding technology for on-site repair. Using the company's independently developed mobile repair equipment, it can directly repair the defects of the runner body. The operation is simple and convenient. Mechanical properties can greatly extend the service life of parts.
