NDT Methods We Use: Quick Reference
AMT uses three primary types of NDT inspection methods: fluorescent penetrant, magnetic particle, and radiographic film inspection. Each is NADCAP-accredited, and each is carried out by our Level I, II, and III technicians.
Use the chart below to learn more about the differences between our non-destructive testing methods. For more in-depth information on each process, view our testing process page.
| Method | Detects | Applicable Materials | Notes |
|---|---|---|---|
| Fluorescent penetrant inspection (FPI) | Surface-breaking cracks, laps, and porosity open to the surface | Most non-porous materials, including nonferrous metals | Level 3 high-sensitivity penetrant; inspected under ultraviolet light |
| Magnetic particle inspection (MPI) | Surface and slightly subsurface discontinuities | Ferromagnetic materials such as iron, nickel, and cobalt alloys | Sensitive to shallow cracks and linear indications |
| Radiographic film inspection | Internal shrinkage, inclusions, voids, and cracks | Dependent on part thickness and density | Produces a permanent film record of part quality |
Why Use an Independent Laboratory for Your NDT Requirements?
An independent lab has no stake in whether a part passes. That separation allows for deeper confidence in the results from all parties. Read more about our approach on our About Us page, or review background material in our resources section. When you partner with AMT for your NDT services, you can count on:
- NADCAP accreditation: Covers every NDT method we perform in-house
