Analysis of Magnetic Mark Display in Magnetic Particle Testing

Abstract:

Magnetic particle testing is based on the magnetic mark of magnetic particle formation on the workpiece surface by magnetic leakage field to reflect the characteristics of workpiece defects. The formation of magnetic leakage field, the impact factors and the distribution characteristics of different defects are discussed. The methods of magnetic mark record are elaborated. The magnetic marks related display characteristics of various types of defects caused, the magnetic marks unrelated display characteristics of the various types of non-defects caused, the pseudo display characteristics are analyzed in detail. Finally the recognition methods of magnetic mark display are given.
