ABSTRACT:
A method of inspecting a component includes immersing the component in a coupling medium with material velocity cwand immersing an ultrasonic (UT) probe having at least one transducer in the coupling medium. The UT probe has a convex lens with acoustic velocity cLand an acoustic impedance less than about 2.5×106Rayls. The method further includes exciting the transducer to produce an UT pulse directed into the component and generating echo signals using the transducer as a receive element. An US inspection system includes UT probe, a pulser/receiver configured to supply signal excitation pulses to the transducer element at a pulse repetition frequency (prf) of at least about 1000 Hz and a scanner configured to scan the component with the UT probe at a scanning rate equal to the prf times a scanning increment.
