Abstract

The invention discloses a rapid scanning method and system for detecting microcracks on the surface of pressure equipment, and the scanning system at least comprises a probe combination which comprises probes with similar signal sensitivity but reduced spot size in equal ratio, wherein each probe has a working mode and a standby mode during detection; an excitation signal generator module and a displacement driving module which control the working probe to scan the surface of the detected body; a signal conditioning module, wherein the working probe receives a feedback signal of the surface of the detected body, converts the feedback signal into an electric signal and inputs the electric signal into the signal conditioning module; a signal acquisition module which is used for receiving the conditioned signal; an output module which is used for outputting a final scanning result; and a manual operation input module which provides a manual control input function. According to the method and the system, the scanning distance with the same defect resolution is greatly shortened, the scanning height is linear, the method and the system are suitable for computer processing planning, and the execution reliability can be relatively better guaranteed.

Description

Technical field[0001]The present invention relates to a rapid scanning method and system for detecting surface microcracks of a pressure device, belonging to the field of early detection technology.Background technique[0002]Metal and other material fatigue is an irreversible structure damage caused by circulating stress. According to statistics, 90% of mechanical accidents and metallic fatigue, including more than 60% of the aircraft crash and industrial equipment explosion. Fatigue accumulation is the direct cause of the structure suddenly breaking and even exploding. Material fatigue is also coupled to corrosion, stress corrosion. This is the phenomenon of failure under the effect of the corrosion environment and the stress, which is the main form of environmental fracture failure in nuclear power structural materials (several alloys).[0003]Metal and other materials are difficult to predict, and actually some extent is unpredictable. There are many factors affecting fatigue failur...
