Ultrasonic Testing uses ________ sound energy to conduct examinations and make measurements.
Ultrasonic Testing uses (high frequency) sound energy to conduct examinations and make measurements.
Ultrasonic inspection can be used for flaw _______, Dimensional _______ and material _______.
Ultrasonic inspection can be used for Flaw detection/Evaluation, Dimensional Measurements, and material characterization.
A pulser/receiver is an electronic device that can produce _____ electrical pulses.
A pulser/receiver is an electronic device that can produce (high voltage) electrical pulses.
Driven by the _____, the transducer generates high frequency ultrasonic energy. The sound energy is introduced and propagates through the materials in the form of _____.
Driven by the (pulser), the transducer generates high frequency ultrasonic energy. The sound energy is introduced and propagates through the materials in the form of (waves).
When there is a _____ (such as a crack) in the wave path, part of the energy will be _____ back from the flaw surface.
When there is a (discontinuity) (such as a crack) in the wave path, part of the energy will be (reflected) back from the flaw surface.
A reflected wave signal is transformed into an _____ signal by the transducer and is displayed on a screen.
A reflected wave signal is transformed into an (electrical) signal by the transducer and is displayed on a screen.
Signal travel time can be directly related to:
the distance that the signal traveled
