Magnetic Particle Testing

Locating Surface Flaws on Magnetized Materials

Magnetic Particle TestingMagnetic Particle Testing, also frequently referred to as Mag Particle Testing, MPI Testing and Magnaflux Inspection, identifies surface flaws in metal products that can be magnetized. The magnetic particle testing services performed at Laboratory Testing Inc. may be applied to raw materials, semi-finished materials such as castings and forgings, finished materials and welds.

Mag particle testing is performed with either a wet solution or a dry powder containing small magnetic iron particles. When these small particles are applied to the surface of the test material, either during or after magnetization, they will be attracted to the magnetic field. The attraction to the magnetic field causes the particles to accumulate in flaws such as cracks, laps and seams, where they will be visible to a trained and certified NDT Inspector.

Mag Particle Testing Methods

Wet fluorescent magnetic particle testing is performed most often at Laboratory Testing Inc. with a solution of very small particles contained in a liquid carrier. The wet solution has an advantage over the dry in that it is easily sprayed, flows well to small leakage fields and the fluorescence allows the particles to be seen without difficulty under our special lighting.

The Lab’s Magnaflux inspection equipment is designed for fast and reliable testing. These machines provide a maximum output of 6,300 amps and can handle products that are up to 12 ft. long.

LTI also performs MPI testing using the visible dry powder method, when wet fluorescent magnetic particle testing is not an option for oversized products.

Magnetic Particle Testing Summary

  • MPI Testing Methods – dry powder and wet fluorescent magnetic particle testing
  • Size Limitations – products up to 12 feet in length
  • Product Requirements – ability to be magnetized
  • Test Supplies – Magnaflux brand
  • Test Specifications – ASTM E1444, MIL-STD-1949, MIL-STD-271, MIL-STD-2132, AMS 2300 Series

RNDT provides industrial radiographic testing services in both our laboratory and in the field at customer locations. We have traditional film based and digital computed radiographic testing services. Our custom built mobile darkrooms are easily set up in less than 10 minutes. We have several exposure vaults that allow for very large parts to be examined. We have several X-ray cabinets for small parts such as electronic chips. Also, we provide high volume processing of film with state-of-the-art ecologically friendly automatic processors. Our Level II and Level III radiographers are experienced in many different specialty techniques involving geometrically challenged parts.

Industrial radiography involves the use of penetrating X- or gamma radiation to examine parts and products for flaws that could be detrimental to their intended use. An X-ray machine or radioactive isotope is used as a source of radiation. Radiation is directed through a part onto a film or an electronic device (plate). When the film or plate is processed, a negative-like picture is obtained that shows the internal characteristics of a part. Possible imperfections show up as density changes in the film, in much the same way an x-ray can show broken bones.

Ultrasonic testing uses the transmission of high frequency sound waves into a material to detect imperfections within the material or changes in material properties. The most commonly used ultrasonic testing technique is pulse echo wherein sound is introduced into the test object and reflections (echos) are returned to a receiver from internal imperfections or from geometrical surfaces of the part.

Our Level II and Level III certified UT technicians work to many codes in many industries. From thickness readings on ASTs to performing full length ultrasonic examinations on 40′ long seamless pressure vessels.

Liquid Penetrant testing is probably the most widely used NDT method. The test object or material is first cleaned and then coated with a visible or fluorescent dye solution. After a pre-selected time interval (dwell time), the excess dye is removed from the surface, and then a developer is applied. The developer acts like a blotter and draws penetrant out of imperfections which are open to the surface. With visible dyes, the vivid color contrast between the penetrant and the developer makes the “bleedout” easy to see. With fluorescent dyes, an ultraviolet lamp is used to make the “bleedout” fluoresce brightly, thus allowing the imperfection to be seen readily.

With a wide variety of penetrant materials and a custom made fluorescent penetrant inspection system, we can provide both field and lab, high volume processing of many different parts with both fluorescent and visible penetrants.

Magnetic particle testing is done by inducing a magnetic field in a ferro-magnetic material and dusting the surface with iron particles (either dry or suspended in a liquid). Surface imperfections will allow the magnetic field to leak out of the part, distort the magnetic field and concentrate the iron particles near imperfections, thus indicating their presence.

Magnetic Particle Testing, or Magnaflux as it is sometimes called, uses magnetic leakage fields to detect surface and subsurface cracks and discontinuities.

Our Magnaflux 6000 amp bench units with 8′ head stocks, portable power packs, yokes, prods, black lights and all required accessories provide the foundation for RNDT to provide quality MT visible and fluorescent, wet and dry examinations in both the lab and field.

Magnaflux MPI.


Magnetic Particle Inspection (MPI) is a relatively low cost, yet highly effective non-destructive testing method used to identify surface and near-surface defects in ferrous metal parts or components, including castings, forgings, weldments and machined or stamped parts.

Magnaflux MPI

At ATRONA, we conduct fast and efficient wet magnetic particle inspection on a daily basis and employ a systematic approach in accordance with ASTM E1444 guidelines. This process begins before actual testing commences...


  • Review provided part specifications and prints to determine if criteria can be met.
  • Level II techs develop a technique that meets customer and test specification requirements for proper inspection.
  • Technique is reviewed by a Level III inspector and revised/approved as needed.
  • Once approved testing can commence.

Following approval of a technique that will meet the customer’s test specification requirements, our certified techs begin testing.


  • STEP 1 - Clean part as needed with a solvent degreaser so it’s free of oils and contaminants.
  • STEP 2 - Secure part between head and tail stock of wet bench machine. Using a “head shot,” a pre-determined amount of electrical current is applied to magnetize the part according to the standard (ASTM E1444). Some test specifications call for multiple head shots.
  • STEP 3 - Bathe part in wet flourescent suspension solution that contains iron oxide particles, as an electric current is applied.
  • STEP 4 - With the magnetic bench machine enclosed within a darkroom enclosure, UV light is applied to identify indications of any defects that appear in relation to the direction of the magnetic field applied to the part.
  • STEP 5 - Depending upon the specific test requirements, one or more “coil shots” may also be applied to the part to identify any discontinuities that run in the opposing direction.
  • STEP 6 - Demagnetize the part.
  • STEP 7 - Following this thorough visual examination, the part is accepted or rejected, based upon pre-defined criteria. Failed parts are isolated from accepted parts and tagged accordingly.

Let ATRONA exceed your expectations for magnetic particle inspection. Our newly expanded MPI area is designed for optimum work flow with three Magnaflux benches operated by certified techs, thousands of square feet of available floor space to store incoming and outgoing parts, as well as an adjacent ground level dock for ease of access. In addition, as a full-service lab, ATRONA has expert metallurgists on staff available for consultation when issues arise. They can also perform additional testing, if necessary, to assess the severity or root cause of any detected indications.
