Description
Technical Field
The invention relates to the field of nondestructive testing, in particular to a TOFD nondestructive testing scanner.
Background
The TOFD detection technology, namely the ultrasonic detection technology by a diffraction time difference method, is an ultrasonic detection technology capable of accurately measuring the size of a defect. The TOFD detection technique is based on the Huygens principle: each point on the sphere is regarded as a wavelet source of a subspheral wave, the velocity and frequency of the subspheral wave are equal to those of the main wave, and the envelope of each wavelet surface is the total wave surface at that time. When the ultrasonic wave is incident to a linear design defect, different diffraction waves can be generated at two ends of the defect under the influence of common reflected waves, and diffraction energy can be transmitted in a large-angle range. Based on the principle, the TOFD technology mainly adopts two longitudinal wave inclined probes with the same frequency, angle and wafer size, wherein one probe transmits signals, and the other probe receives signals. When detecting defects, the two probes are parallel to the same horizontal plane and symmetrically cross two sides of the detected object in opposite directions. When a defect exists, the receiving probe receives the transverse waves generated at the defect point and the bottom surface due to the waveform conversion, and the transverse waves arrive at the receiving sensor later than the reflected waves of the bottom surface. In addition to the above waves, the receiving probe receives not only the diffracted waves and the reflected waves generated at the defect but also the through waves and the bottom surface reflected waves. The transverse longitudinal wave of the weld impacts the defect, producing a diffracted wave at the end of the defect. If the defect has sufficient internal height, the signals at the two ends of the defect will differ in time, and the height of the defect can be determined from the difference in the propagation times of the recorded diffraction signals. The welding structure is the basic structure of modern industrial large-scale equipment, and the working environment of the large-scale equipment is often accompanied by severe conditions such as high temperature and high pressure. Cracks can occur over the life of the product due to imperfections and residual stresses in the welding process, which can have catastrophic consequences. Therefore, appropriate analysis is carried out by using the information technology of nondestructive testing and monitoring, the defects of the welding structure of the equipment can be found in advance, the operation risk of equipment management can be evaluated in time, and contribution is made to the safe operation of debugging equipment of the whole business project.
