The utility model relates to a device for automatically detecting a weld joint of a low-pressure welding rotor of a steam turbine for a nuclear power station. The device comprises a guide rail assembly, a circumferential motion assembly, an axial drive assembly, a probe assembly and a circumferential drive assembly. The guide rail assembly is of a circular ring guide rail structure, and the direction of an opening of a guide rail groove is the same as the direction of the axis of the circular ring rail structure. The circumferential motion assembly is embedded into the guide rail assembly and slides along the circular ring guide rail structure. The circumferential drive assembly is matched with the circumferential motion assembly and drives the circumferential motion assembly to slide in the circumferential direction. The axial drive assembly is connected with the circumferential motion assembly and comprises a sliding part which slides in the direction of the axis of the circular ring guide rail structure, a
