【 摘 要 】

Bolt connection is widely used in hydraulic power plants as an important connection mode of metal parts. However, the phenomenon of bolt breakage often occurs in hydropower plants, which seriously affects the stable operation of hydropower plants. During the maintenance of the unit, non-destructive testing of high-strength bolts is able to effectively detect the bolt defects and ensure the safety of the unit.
