Description

(54) СПОСОБ УЛЬТРАЗВУКОВОГО КОНТРОЛЯ ИЗДЕЛИЙ(54) METHOD OF ULTRASONIC CONTROL OF PRODUCTS

3 Предмет изобретени 3 Subject of the invention

Способ ульразвукового контрол  изделий с эквидестантными поверхност ми, заключающийс  в том, что производ т поверхность конролируемого издели  скандируют двум  иаклонными искател ми при параллельном размещении их осей, периодически излучают ультразвуковые импульсы обоими искател ми, принимают ими эхо-сигналы из издели  и регистрируют эхо-сигналы, зеркально-отраженные от дефекта и от поверхности издели , отличающийс  тем, что, с целью повышени  точности контрол , дополнительно регистрируют обратно отраженные к каждому искателю эхо-сигналы от того же дефекта, сравнивают между собой амплитуды всех регистрируемых эхо-сигналов и по знаку и величине амплитрудной разности между зеркально-отраженным и обратно отраженным эхо-сигналами суд т о характере дефекта.The method of ultrasonic testing of products with equidistant surfaces, which consists in producing the surface of a controlled product by chanting two scanners while parallelly placing their axes, periodically emit ultrasonic pulses by both searchers, receive their echo signals from the product and record the echo signals , specularly reflected from the defect and from the surface of the product, characterized in that, in order to increase the accuracy of control, they additionally register back reflected to each searcher ho-signals from the same defect, compared between the amplitudes of all the echo signals detected and the sign and magnitude of the difference between amplitrudnoy specularly reflected and back-reflected echoes judged on the nature of the defect.
