Background
Ultrasonic flaw detectors are widely used, but in the actual flaw detection process, pulse reflection type ultrasonic flaw detectors are most widely used. Generally, in a uniform material, the existence of defects causes discontinuity of the material, the discontinuity often causes inconsistency of acoustic impedance, and the reflection theorem shows that ultrasonic waves are reflected on an interface of two media with different acoustic impedances, the amount of energy reflected back is related to the difference of the acoustic impedances of the media on two sides of the interface and the orientation and the size of the interface, and the pulse test ultrasonic flaw detector is designed according to the principle.
Most of the conventional portable ultrasonic flaw detectors are of an a-scan type, in which the abscissa of a display is the propagation time or propagation distance of ultrasonic waves in a material to be detected, and the ordinate is the amplitude of a reflected ultrasonic wave. A flaw exists in a pipeline workpiece, due to the existence of the flaw, an interface between different media is formed between the flaw and a material, acoustic impedances between the interfaces are different, when transmitted ultrasonic waves meet the interface, the ultrasonic waves are reflected, the reflected energy is received by a probe, a waveform of a reflected wave is displayed at a certain position of an abscissa in a display screen, the position of the abscissa is the depth of the flaw in the detected material, and the height and the shape of the reflected wave are different due to different flaws, so that the nature of the flaws is reflected.
When the portable ultrasonic flaw detector with the double probes is used for detecting the defects of the pipeline, the detection range of the probes is smaller, and operators need to hold the two probes respectively with two hands to monitor the pipeline or the two operators work in a cooperative mode, so that the detection efficiency is lower.
