Which of the following is NOT an advantage of NDT?
Tests can be repeated on the same item
Equipment is often portable for field use
Requires large capital investment
Little or no specimen preparation is required
What is a limitation of NDT?
It cannot be used on parts in-service
It requires complete disassembly of components
Results must often be interpreted by a skilled technician

What is the principle behind magnetic particle testing?
Using magnetic fields to detect surface cracks
Using sound waves to detect flaws
Using radiation to create an image of the component
Using dye to highlight surface defects
What is a disadvantage of ultrasonic testing?
It cannot be automated
It requires access to both sides of the part
It is not sensitive to small flaws
