Claims (1)

Способ ультразвукового контроля сварных стыков рельсов, заключающийся в том, что на поверхность катания рельса устанавливают ультразвуковой измерительный блок, содержащий несколько измерительных элементов, каждый из которых по соответствующим схемам прозвучивания способен обнаружить дефекты в определенной зоне сварного стыка рельса, последовательно зондируют сварной стык рельса измерительными элементами, для чего излучают зондирующие и принимают отраженные от возможных дефектов ультразвуковые сигналы, отличающийся тем, что на выбранные участки поверхности рельса устанавливают несколько ультразвуковых измерительных блоков, которые неподвижно закрепляют на них, выбирают дополнительные схемы прозвучивания между измерительными элементами, схемы прозвучивания измерительных элементов выбирают так, чтобы они совместно позволяли обнаружить дефекты во всем сечении сварного стыка рельса с заданной разрешающей способностью, при зондированиях измеряют амплитуды и временное положение отраженных сигналов, вычисляют пространственное положение дефекта, объединяют и отображают результаты всех зондировании, по которым оценивают их и принимают решение о качестве сварного стыка.The method of ultrasonic testing of welded joints of rails, which consists in the fact that an ultrasonic measuring unit containing several measuring elements, each of which is capable of detecting defects in a specific area of the welded joint of a rail, is subsequently probed by a welded joint of the rail with measuring elements for which they emit sounding and receive ultrasonic signals reflected from possible defects, characterized in that you early sections of the rail surface are installed by several ultrasonic measuring units, which are fixedly mounted on them, additional sounding schemes are selected between the measuring elements, the sounding schemes of the measuring elements are chosen so that they together allow to detect defects in the entire section of the welded joint of the rail with a given resolution when probing measure the amplitudes and temporary position of the reflected signals, calculate the spatial position of the defect, combine and about They represent the results of all soundings, according to which they are evaluated and a decision is made on the quality of the welded joint.
