How to Conduct Ultrasonic Testing
In general, Ultrasonic Testing uses sound waves to detect defects or imperfections on the surface of a material created.
One of the most common Ultrasonic Testing methods is the pulse echo. With this technique, inspectors introduce sounds into a material and measure the echos (or sound reflections) produced by imperfections on the surface of the material as they are returned to a receiver.
Here are some other types of Ultrasonic Testing:
- Phased Array Ultrasonic Testing (PAUT)
- Automated Ultrasonic Testing (AUT)
- Time-Of-Flight Diffraction (TOFD)
