Question 79

The best method to inspect for SCC is ____.

    Correct Answer: A

    Wet fluorescent magnetic particle testing (WFMT) is considered the best method to inspect for stress corrosion cracking (SCC). This technique is highly sensitive to detecting surface-breaking cracks, which are typical in SCC. It involves applying a fluorescent magnetic particle suspension to the surface of a ferromagnetic material and using ultraviolet light to detect any indications.

Discussion

Wet fluorescent magnetic particle testing (WFMT), alternating current field measurement (ACFM), and eddy current testing (ECT) can be effective techniques to detect these surface-breaking cracks.
