Magnetic Particle Testing

Magnetic Particle Testing

Magnetic Particle Testing is a quick, cost-effective NDT inspection method that is used to detect surface and near-surface discontinuities. This method is available both in the field and in the lab. Bureau Veritas Inspectors magnetize a ferromagnetic material and apply finely milled iron particles coated with a dye pigment to it. The particles indicate a discontinuity or indication in the material by clustering directly over it. Which can be visually detected under the proper lighting conditions.

Bureau Veritas uses both methods (Dry Powder and Wet Fluorescent Magnetic Particle) to find surface or near-surface defects in ferromagnetic material. The MT method requires a skilled technician to distinguish between relevant and non-relevant indications. It is often used to detect metal cracking, weld verification and stress corrosion cracking, which can be seen by using magnetic particles that are drawn into the discontinuity.
