INCREASING THE EFFICIENCY OF EDDY CURRENT DEFECTOSCOPY WHEN REGISTRATION OF SIGNALS FROM TWO SPATIAL COMPONENTS OF THE MAGNETIC FIELD
(pp. 4-14)

Abstract. The paper is devoted to increasing the information content of eddy current signals from defects using a two-channel eddy current probe. The design of a new two-channel eddy current probe recording the tangential and axial components of the magnetic field of a defect is described. It is shown that when recording the axial component of the magnetic field of a defect instead of the usually recorded normal component, greater efficiency of flaw detection is achieved. The new two-channel probe is studied using mathematical modeling based on the finite element method.

Keywords: eddy current flaw detection, increasing efficiency, two-channel eddy current probe, axial component, tangential component.
