  • Publication number: 20260104389
    Abstract: A mosaic distributed combined interval magnetization method includes: arranging a magnetization module including magnetic sources disposed at both ends of a yoke and having opposite magnetic properties; arranging a magnetic sensor disposed between the two magnetic sources, where the magnetic sensor is used to detect changes in a direction of a magnetic field of the test piece under detection; wrapping the yoke and the magnetic source to form a non-metallic wrapped structure of a detection component, where the magnetization module is divided into a first magnetization module and a second magnetization module which is symmetrically disposed about a center of the first magnetization module. The method solves the problem of inaccurate detection signals caused by defect diversity, thereby ensuring that defect classification and defect quantification will not occur during subsequent data analysis, which otherwise leads to problems such as unclear defect classification and inaccurate defect quantification.
