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.

结构钢薄板的多频涡流检测

研究了涡流探头对被测物体表面的压力等参数对结构钢板涡流检测结果的影响。用多频测量得到的ECP附加电阻的实验值来隔离待测参数。确定了这些阻力与压紧力和表面安装涡流探头的钢板厚度的关系。提出了一种涡流测量结果的处理方法，保证了干扰参数的抑制和被测参数的可靠隔离。

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).
