| Abstract: | Fracture analysis of the fan shaft was made by observing macroscopic and microscopic appearances of the crack,and examining micro hardness and chemical composition of the material.The result shows that the main reason for the fracture of the shaft is low stress fatigue resulting from the welding defect in the surface of the fan shaft. |

| Keywords: | fan shaft low stress fatigue welding defect |
