Description

technical field [0001] The invention relates to the field of ultrasonic monitoring, in particular to a device, system and identification method for multi-angle ultrasonic monitoring of solid defects. Background technique [0002] Large-scale large-scale steel parts in service have been affected by tension, compression and shear force for a long time, and there are repeated changing stresses inside the structural parts. If they are in service for a long time, a series of defects (mainly cracks) will be generated inside the structural parts. These cracks are harmful to safety. The relationship between production and operation is very serious, which seriously threatens the safety of life and property. Traditional defect detection methods are mainly manual operations, using eddy current, ultrasonic, X-ray and other non-destructive testing methods. These methods are relatively simple, and most of them are high-altitude operations. It is impossible to realize automatic real-time ...
