Welding Ultrasonic Testing. High-frequency sound waves are sent into the material with an ultrasonic transducer. The Ultrasonic Testing UT Level I course includes a basic introduction to the theory and principles of ultrasound including frequency velocity and wavelength.
Introduction It is not uncommon for a nondestructive testing ultrasonic technician to inspect structural welds according to the American Welding Society D11. Today we are back at Ocean Corporation learning about Ultrasonic testing and how it is used to test welds. The Ultrasonic Testing UT Level I course includes a basic introduction to the theory and principles of ultrasound including frequency velocity and wavelength.
Ultrasonic testing is a family of non-destructive testing techniques based on the propagation of ultrasonic waves in the object or material tested.
It addresses the variables related to the propagation reflection and attenuation of sound as well as the responses from discontinuities. The parts to be welded are placed in the anvil or fixture. The Ultrasonic Testing UT Level I course includes a basic introduction to the theory and principles of ultrasound including frequency velocity and wavelength. Weld bead interfere with the ultrasonic test or cause diffi- culties in interpretation then the weld bead should be ground reasonably smooth.
