A non-destructive testing method used to detect surface and near-surface flaws in ferromagnetic materials.
Key Points:
Involves magnetizing the material and applying magnetic particles.
Particles gather at flaw locations, revealing cracks or defects.
Effective for detecting fine surface cracks not visible to the eye.
Quick, reliable, and widely used in welding and fabrication.
Only applicable to materials that can be magnetized (e.g., steel, iron).
