Embodiment Construction

[0017] exist figure 1 , figure 2 In the shown embodiment, the eddy current impedance plane detector is used to detect the discontinuity of non-metallic materials, and the characteristics of the distribution and magnetic induction intensity of the magnetic field 3 caused by the change of the medium in the magnetic field 3 are used, and the eddy current impedance plane detector is used to detect non-metallic materials. Discontinuity in metallic materials; according to the magnetic induction formula =μ 0 mu r , it can be known that the magnetic induction The relative permeability of the medium in the magnetic field μ r related, and the relative permeability μ of the medium r and relative permittivity ε r Related, when there is a discontinuity in the medium, the relative permittivity ε of the medium r will change, causing the distribution of the magnetic field 3 and the magnetic induction intensity to change, thereby causing the impedance of the detection coil in the e...

Abstract

The invention discloses a method for detecting the discontinuity of non-metallic materials by using an eddy current impedance plane detector. Based on the principle of electromagnetic field, the characteristics of the magnetic induction intensity and distribution of the magnetic field caused by the change of the medium in the magnetic field are used to detect the nonmetal by using the eddy current impedance plane detector. The discontinuity of the material, the invention breaks through the limitation of current non-destructive testing theory, applies the electromagnetic eddy current testing method to the discontinuity detection of non-metallic materials, improves the detection efficiency, and is easy to realize the automatic detection of the discontinuity of non-metallic materials.

Description

Technical field [0001] The invention relates to a non-destructive detection method, in particular to a method for detecting discontinuity of non-metallic materials by using an eddy current impedance plane detector. Background technique [0002] For the discontinuity detection of non-metallic materials, the currently used non-destructive testing methods include acoustic, mechanical, ray and other detection methods. Electromagnetic nondestructive testing methods are currently only used for discontinuity detection in metallic materials. Among the electromagnetic nondestructive testing methods, the eddy current testing method has the advantages of high detection accuracy, fast detection speed, and easy automatic detection compared with acoustic, mechanical, and ray detection methods. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a method for detecting discontinuity of non-metallic materials...
