A Method of Eddy-Current Flaw Detection of Bars and Tubes Based on the Use of a Combined Eddy-Current Transducer with Excitation of Spatial Magnetic-Field Components at Different Frequencies

摘要

The possibility of using the method of eddy-current testing using a combined multisec-tional transducer with a heterofrequency magnetic field is described. The technological implementa-tion of this method for detecting flaws in bars and tubes under the conditions of significant transverse displacements is described.
