... ( Ref 15.18 ). These stress waves are accompanied by an acoustic emission. The acoustic emission excites a piezoelectric transducer that produces an output voltage, thereby indicating a crack in the workpiece or breakage in the tool ( Fig. 15.15 ). Fig. 15.15 Principle of acoustic emission sensor...

.... Acoustic emission (AE) testing and leak testing are described separately, because they are somewhat different in character and are not used as widely. There are other NDE methods that have been omitted because they are very specialized. Applications A useful distinction can be made between those NDE...

... and resolution. A 5 or 10 MHz dual element transducer is normally used in this application. If the weld cannot be machined, near surface sensitivity will be low because the initial pulse is excessively broadened by the rough, as-welded surface. Unmachined welds can be readily inspected by direct beam...
