Study Notes
- Ultrasonic Testing (UT) uses high frequency sound energy for examinations and measurements.
- UT can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more.
- A typical UT inspection system consists of pulser/receiver, transducer, and display devices.
- A pulser/receiver produces high voltage electrical pulses, and the transducer generates high frequency ultrasonic energy.
- The sound energy is introduced and propagates through materials in the form of waves.
- When there is a discontinuity in the wave path, part of the energy will be reflected back from the flaw surface.
- The reflected wave signal is transformed into an electrical signal by the transducer and is displayed on a screen.
- Ultrasonic Inspection is a versatile NDT method with advantages and limitations.
- UT advantages include high accuracy, non-destructive, and fast inspection.
- UT limitations include the need for skilled operators, limited penetration depth, and sensitivity to surface conditions.
