Question: 1 / 400

Which NDT method uses sound waves to detect flaws?

Magnetic Particle Testing

Liquid Penetrant Testing

Ultrasonic Testing

Ultrasonic Testing is the method that employs sound waves for the detection of flaws within materials. This technique is based on sending high-frequency sound waves into the material being tested. When these sound waves encounter a flaw, such as a crack or void, they are reflected back to the transducer. The time it takes for the sound waves to return, along with the characteristics of the returned signals, helps in determining the presence, size, and location of the flaws.

The use of sound waves in Ultrasonic Testing offers several advantages, including excellent sensitivity to small defects and the ability to provide volumetric analysis of the materials. This method is widely utilized in various industries for its effectiveness in ensuring integrity and safety in structural components.
