Features of Ultrasonic Testing
Do you know which technology is used to detect metallic discontinuity or detect cracks?
Are you curious to know about the ultrasonic sensor? If yes, it is the Ultrasonic Testing technology used in several industries for various purposes.
What is Ultrasonic Testing?
Ultrasonic testing is a non-destructive testing method that uses ultrasonic waves to detect anomalies in material. High-frequency ultrasonic wave is transmitted into the material to detect flaw.
How does it work?
Ultrasonic testing uses piezoelectric transducer that transmit ultrasonic (sound) wave into the material and the reflected wave is received by the receiver. Time taken for the ultrasonic wave to travel into the material and reflected from the backwall is measured to determine the thickness of the material. Any discontinuities of wave in between are identified as flaws or defects.
Transducers for wave transmission and detection
The transducer in an ultrasonic sensor that transmit ultrasonic wave is transmitter and that receive the wave is receiver.
Eight qualities of the Ultrasonic Testing
- Able to determine thickness and estimate size and defects
- Provide Immediate results upon testing
- High accuracy when compared to other NDT methods for determining flaws and depth
- Non hazardous to personnel
- Sensitive to both surface and subsurface discontinuities
- High depth penetration to detect deeper flaw within the material
- Only one side access is required to perform testing
- High sensitivity to air void that is suitable to detect small flaws
Summing Up
Ultrasonic testing has a wide application across industries, especially in testing the integrity of a material. Testing can be applied on both ferrous and non-ferrous materials, as well as thin and thick materials. There are many ultrasonic testing systems available in the market. Thus, use a supplier who has the expertise to recommend appropriate system to your applications.
