What is TOFD?

TOFD, or Time-of-Flight Diffraction, is an advanced ultrasonic testing method used to detect flaws in welds and other materials. It relies on measuring the time-of-flight of diffracted ultrasonic waves from the tips of flaws, providing accurate flaw sizing and location information. It's commonly used in industries requiring high precision flaw detection, such as oil and gas, aerospace, and nuclear.
