3 Terms and Definitions

GB/T 12604.5 and GB/T 12604.6 defined and the following terms and definitions apply to this document. 3.1 Defects equivalent defectequivalent With a particular value or common law equivalent amount, in accordance with this standard is specific signal characteristics obtained given the magnitude of the defect. 3.2 Defects quantization defectsizing According to signal characteristics obtained are given defect geometry description. 4. Summary 4.1 Principle of magnetic flux leakage detection method The principle of magnetic flux leakage testing shown in Figure 1. When the ferromagnetic member is applied magnetizing, generates a magnetic field within the member, if the member The presence of corrosion or mechanical damage and other defects, the magnetic field lines will leak to the outside member, thereby forming a leakage magnetic field on the surface, as in the middle of magnetizer Place - a magnetic field sensor (usually a Hall element or a magnetic field sensor coil) can be detected by the leakage magnetic field due to the leakage magnetic field strength The depth and size of the defect, it can signal by the leakage magnetic field analysis to obtain the occurrence of defects on the member. Figure 2 is the measured Different amounts of magnetic field components of a typical signal Fig. ......
