Increase of the Informative Value of Magnetic Nondestructive Testing Using Vibration Induction Transducer on the Basis of Spectral Analysis

The ways of increasing the information content of magnetic flaw detection based on spectral analysis when registering magnetic fluxes of leakage from defects by a vibration induction probe (VIP) are considered. It is shown that the VIP signals, caused by the normal and tangential components of the strength of the magnetic scattering fluxes, are linearly independent, and the corresponding harmonic components of the spectra of these signals are weakly dependent on the noise component and carry information about the coordinates and parameters of the defect.

Analysis and Exclusion of Magnetization Failure on CJW-3000 Magnetic Flaw Detection Machine

This paper analyzes the common faults in the magnetization process of CJW-3000 Magnetic Flaw Detection Machine and gives exclusion methods. In line with the principles of the easier issues first, by starting the analysis from Circuit Drawings, we can increase maintenance efficiency and avoid doing too much exercise in futility.
