Description

эхо-сигналы, отраженные от дефекта .и обратной стороны издели , а по их амплитуде суд т о величине и форме дефекта. Таким образом, изменение частоты в зависимости от местоположени  зоны контрол  относительно кра  и издели  обеспечивает учет вли ни  интерференционных  влений на амплитуду донного эхо-сигнала, cвидeтeльcт вук дего о состо нии качества акустического контакта при контроле краевых зон толстостенных изделий, а следовательно , и возможность -корректировки амплитуды эхо-сигнала от дефекта при изменении качества акустического контакта, что повышает качество контрол .echo signals reflected from the defect and the back side of the product, and by their amplitude judge the size and shape of the defect. Thus, a change in frequency depending on the location of the control zone relative to the edge and the product takes into account the influence of interference effects on the amplitude of the bottom echo signal, seeing the quality of the acoustic contact when monitoring the edge zones of thick-walled products, and hence the possibility of adjusting the amplitude of the echo signal from the defect when the quality of the acoustic contact changes, which improves the quality of the control.
