Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

The digital technologies get ever wider application in various fields of engineering, including also in radiation control of quality of welded joints. In the work a high flaw detection efficiency of flash radiography and radiography without intermediate information carriers (films, memory plates) is shown, providing a low cost and ability to multi-angle real-time monitoring of inner defects of welded joints. At the same time the speed of control is significantly reduced. The portable equipment for implementation of this technology is described allowing achieving the sensitivity of up to 0.1 % of thickness of the inspected metal and resolution exceeding 10 pairs of lines per millimeter. 11 Ref., 4 Figures.
Keywords: non-destructive testing, flash radiography, digital image, X-ray TV system, scintillator, CCD array, flat panel detector, inner defects of welded joints
