Magnetic Particle Inspection
Magnetic Particle Inspection: Magnetic Particle Testing (also called magna-flux testing) is a nondestructive test method used to detect problems at or near the surface in ferromagnetic materials. NIS conducts magnetic particle testing for items such as:
- Eyebolts
- Crane hooks
- Welds on specialty lifters
- Swivel hoist rings
- End Effectors
- Hi-Lo Forks
The process for magnetic particle testing at NIS is outlined below:
- Physical characteristics of the test item (size, type, serial number, etc.) are recorded on an inspection report.
- Test item is inspected visually for elongation, wear, deformation, and missing capacity markings.
- The part is cleaned with a special cleaner to prepare it for magnetic particle testing.
- The part is magnetized.
- The part is sprayed with a magnetic particle spray.
- After the part has been prepared with the particle spray, it is inspected for cracks by a certified technician using a black light and magnetic yoke.
- The technician having made the necessary observations, the part is demagnetized and cleaned.
- Each passing test item is tagged with a color coded inspection tag, demonstrating that it has been checked.
- Test items which do not pass inspection will be tagged with a caution tag as well as a red paint mark.
- Lastly, NIS provides a computer generated report on a spreadsheet with a certificate governing regulatory standards for all passing test items.
