Abstract
The paper is devoted to the development of a finite element model of an eddy current probe designed to test the degree of soldering in lap-joint soldered connections of conductive busbars. A methodology for developing a finite element model has been devised that includes a geometric parameter that, when altered, leads to the remeshing of the finite element grid without affecting the test parameters of nondestructive testing. This allows for a series of signal measurements of the finite element model of the eddy current probe, followed by averaging, thereby ensuring acceptable accuracy. The test results confirm the functionality of the eddy current probe, with a defect size measurement range in the soldered joint from 0 to 100% and a guaranteed main absolute error in measuring the degree of soldering of 5%.
期刊介绍：
Russian Journal of Nondestructive Testing, a translation of Defectoskopiya, is a publication of the Russian Academy of Sciences. This publication offers current Russian research on the theory and technology of nondestructive testing of materials and components. It describes laboratory and industrial investigations of devices and instrumentation and provides reviews of new equipment developed for series manufacture. Articles cover all physical methods of nondestructive testing, including magnetic and electrical; ultrasonic; X-ray and Y-ray; capillary; liquid (color luminescence), and radio (for materials of low conductivity).
