Abstract
The aim of the study. By taking into account the individual characteristics of magnetic structuroscopes such as KRMCC-2M to increase the reliability of the passport of magnetic control. Research methodology. To take into account the individual characteristics of magnetic structuroscopes such as KRM-CC-2M, a method has been developed. It is based on taking into account the individual characteristics of magnetic structuroscopes. The essence of this method is that together with the crane and PMK you need to have a stepped pattern with different sections of the same material from which the metal structure of the crane. At each magneto-coercive NC of the metal structure of the crane it is necessary to measure the coercive force of this sample and enter them in the PMC together with the serial number of the structroscope. Having readings of the coercive force on this sample of all structuroscopes of the KRM-CC-2M type, it is possible to draw a conclusion about the level of magnetization intensity of each structroscope. Next, calculating the difference in the intensity of magnetization of the devices KRM-CC-2M (ΔNS δ, A / cm), take it into account when processing and analyzing the results already obtained on the crane magnetic-coercive NC. Results. The process of analysis of the results of magnetic coercive control is automated. It is shown that it is impossible to be limited at an estimation of a condition of a metalwork to only one method. For a more objective result, it is necessary to apply magnetic coercive control in combination with other control methods and calculation methods. Work on magneticcoercive non-destructive testing, which solve existing problems, has been confirmed in practice. This will make it possible to conduct magnetic-coercive control of metal structures with different thicknesses of elements, take into account the individual characteristics of magnetic structuroscopes such as KRM-CC-2M and increase the coercive force depending on the load intensity of the metal structure. Practical significance. The results of the research are used in the analysis of the change of coercive force in the bevel of the sprung system of the crane-loader with a capacity of 32 tons.
