Portable Yoke Flaw Detector

The portable yoke flaw detector magnetizes workpieces by generating a magnetic field through the yoke. Surface defects in ferromagnetic materials create leakage magnetic fields, which attract magnetic particles to reveal cracks. It is used for on-site detection of surface and near-surface defects in welds, castings, and forgings, and is commonly employed in the maintenance of steel structures and pipelines.
Selection
When selecting, consider that the material to be tested is ferromagnetic, and the workpiece shape should match the yoke opening size. Determine the lifting force index based on standard requirements. Environmental conditions influence the choice between AC or DC types. Portability involves weight and power supply methods, and magnetic particle compatibility and sensitivity must match the defect type.
