What non-destructive 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?
- Eddy current inspection.
- Magnetic particle inspection.
- Ultrasonic pulse inspection.
Explanation from PART66Online
Eddy current testing induces currents in a conductive surface and reads changes in their flow, needing little or no part preparation and detecting surface and near-surface defects in most metals. Because conductivity and permeability vary with alloy and heat treatment, it can also sort metals and their heat-treat conditions, which the other listed methods cannot do.

isnt eddy current inspecction method only for internal cracks?Why does it mention here that it is used to detect"surface and nearsurface"?
