Magnetic particle testing

It is possible to check for invisible cracks! Suitable for detecting cracks that exist near the surface.

"Magnetic particle testing" can only be applied to ferromagnetic materials that are attracted to magnets. When using the equipment to magnetize a ferromagnetic material (test specimen), a flow of magnetism called magnetic flux is generated within it. If there are cracks or other defects on the surface or near-surface of the test specimen, the magnetic flux will leak into the surface space due to the defects, forming small magnets. When very fine iron powder (magnetic powder) that is colored is sprinkled onto that area, the magnetic powder adheres to the defect, and the adhered magnetic powder becomes a magnet, allowing the magnetic powders to stack and form patterns, which is used to detect the defects. 【Features】 ■ Can only be applied to ferromagnetic materials that are attracted to magnets ■ Utilizes the adhesion of magnetic powder to defect areas, where the adhered magnetic powder becomes magnets, allowing the powders to stack and form patterns to detect defects ■ The aggregation of magnetic powder creates patterns that are enlarged compared to the actual defects ■ Allows for the detection of narrow, invisible defects *For more details, please refer to the PDF document or feel free to contact us.
