摘要：
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.
