Abstract
The results of studying the influence of parameters such as the force of pressing an eddy current probe (ECP) against the surface of a test object on the outcomes of eddy current testing of structural steel sheets are presented. Experimental values of the ECP added resistances obtained through multifrequency measurements were used to isolate the parameter being tested. Dependences of these resistances on the pressing force and the thickness of the steel sheet for a surface-mounted eddy current probe were identified. A method for processing eddy current measurement results is proposed, ensuring the suppression of interfering parameters and reliable isolation of the tested parameter.
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).
