Liquid Penetrant Inspection

Water Washable Liquid Penetrant Inspection

  • A liquid with high surface wetting characteristics is applied to the surface of the part and allowed time to seep into surface breaking defects
  • The penetrant used is often loaded with a fluorescent dye and the inspection is done under UV light to increase test sensitivity

Solvent Removable Penetrant Inspection

  • A spray penetrant is applied to the inspection area
  • The excess penetrant is removed from the surface of the part with the help of a solvent based remover.
  • A developer (powder) is applied to pull the trapped penetrant out the defect and spread it on the surface where it can be seen
