Ultrasonic testing is an NDT technology for detecting test piece discontinuities which may not be visible to the human eye. These defects can include cracks, corrosion, inclusions, porosity outside of specified tolerances, and voids. Ultrasonic testing devices pass ultrasonic sound waves into the test piece and measure the waves that reflect back to the device. The profile of the reflection is interpreted by software and the human operator to determine if the test piece is within spec.
In this article, we’ve interviewed several experts on ultrasonic testing. We hope to provide an overview of this technology and the good which it is doing in the world. We asked our panel of experts the following questions:
- How is ultrasonic testing creating a safer world?
- What advice do you have for someone who wants to start a career in ultrasonic testing?
- What is the most serious flaw you’ve ever detected via ultrasonic testing?
