“…Объектом исследования являлись образцы (темплеты длиной 200 мм) прямошовных электросварных (ВЧС) труб Ø 159×6,0 из стали марки 20 ГОСТ 1050-2013 [1], изготовленные по ГОСТ 10705-80 [2], в которых при рентгенографическом контроле предположительно были обнаружены непровары и трещины в сварном шве, при этом сварные соединения выдержали механические испытания на прочность. Кроме этого, указанные дефекты не были обнаружены при магнитной дефектоскопии данных труб с помощью установки магнитной дефектоскопии УМД-101М в технологической линии производства прямошовных электросварных труб [3][4][5].…”

Defects of longitudinal tube welds identified by X-ray inspection are studied in order to determine possible causes of their occurrence and to assess the reliability of nondestructive testing results. Metallographic analysis shows that the base metal and weld metal meet the requirements of regulatory documents. The strength properties and the chemical composition conform to the standards. The contamination with non-metallic inclusions in the segregation streamers of the sheet extending to the edge and falling into the fusion zone was detected in X-ray photographs and incorrectly interpreted as a defect. This assumption is based on the correlation of X-ray patterns with the position of the grooves in the zones of the studied welded joints, but it ignores the results of studying by other nondestructive testing methods, and most importantly, it is not confirmed by metallographic studies. Neither were these defects found in the tubes during magnetic flaw detection by means of a UMD-101M device in the line of production of longitudinally electric-welded tubes. Erroneous defect identification during X-ray inspection happens in tube making. The results of the study show the expediency of the integrated application of different testing methods for a reliable assessment of the quality of tubes or pipes of both small and large diameters.

“…Если НК ведется на непрерывной трубе, то чаще всего применяются вихретоковые [2, 3] и магнитные дефектоскопы [4][5][6][7][8] (УЗК для решения этой задачи применяется, как правило, только в дорогостоящих импортных установках ротационного типа).…”

To detect the stress of steel structures and members using the existing magnetism, a magnetic stress sensing system integrating a magnetic flux induction coil, a magnetic flux measurement device, a loaded device, and data acquisition software was developed. The magnetic coupling test research was carried out for different grades of structural building and bridge steel specimens to establish the magnetic stress flux mathematical model, and the fitting equation of the magnetic flux changes with the positions of different sections of specimens was analyzed. Furthermore, a practical formula for stress detection was obtained through the experiments. Meanwhile, on these bases, the typical steel truss structure model of a Bailey beam was designed and manufactured under different working conditions, nondestructive online stress testing was carried out, and the stress of the model structure and its members was measured by strain and magnetic flux tests to obtain the curves of the test results for the stress–strain and magnetic stress flux, respectively. The results of these two methods are in good agreement with each other. The stress of the steel truss model structure was analyzed and calculated using the finite element method. The results agreed well with the experimental results from the magnetic stress sensing system—the maximum error was about 5%, which meets the requirements of engineering applications.
