Non-Destructive Testing (NDT) Study Guide & Core Inspection Methods Revision
Notes
Magnetic particle inspection is used primarily to detect - ANS ✔✔flaws on or near the surface
Liquid penetrant inspection methods may be used on which of the following.
1. Porous plastics
2. Ferrous metals
3. Nonferrous metals
4. Smooth primer sealed wood
5. Nonporous plastics - ANS ✔✔2,3,5
Which of these nondestructive testing methods is suitable for the inspection of most metals
plastics and ceramics for surface and subsurface defects - ANS ✔✔Ultrasonic inspection.
What nondestructive testing method requires little or no part preparation, is used to detect
surface or near surface defects in most metals, and may also be used to separate metals or
alloys and their heat-treat conditions? - ANS ✔✔Eddy current inspection.
What method of magnetic particle inspection is used most often to inspect aircraft parts for
invisible cracks and other defects? - ANS ✔✔continuous
How many of these factors are considered essential knowledge for x-ray exposure
1. Processing of the film
2. Material thickness and density
3. Exposure distance and angle
4. Film characteristics - ANS ✔✔Three
