| Abstract: | Chemical composition, mechanical property, macro and micro-scopic structures as well as frac-ture surface of the wreckage of the fractured fan were examined. The results showed that welding defect was the major reason for sudden breaking up of electrostatic precipitator fan. The layer structure defect of the fan blade and front disk materials also was one of the factors related to the accident. |
