  LIMITATIONS OF MAGNETIC PARTICLE INSPECTION

  Posted by sofia on 14/10/2021 at 11:48 am

  • The specimen must be ferromagnetic (e.g. steel, cast iron)

  • Paint thicker than about 0.005″ must be removed before inspection

  • Post cleaning and post demagnetization is often necessary

  • Maximum depth sensitivity is typically quoted as 0.100″ (deeper under perfect conditions)

  • Alignment between magnetic flux and defect is important
