Provides students with foundational knowledge related to nondestructive testing (NDT) and offers the opportunity to gain hands-on training in the NDT method of ultrasonic testing. With this method, NDT inspectors need access to only one side of a material. A transducer sends the ultrasound through the sample and the inner wall of a defect surface will send the wave bouncing back. Ultrasonic testing is a portable and efficient way to measure thickness, detect corrosion, and examine groove welds in many materials.
