What Is Time of Flight Diffraction?
Time of Flight Diffraction (TOFD) is an advanced ultrasonic non-destructive testing method designed to detect, locate, and size internal flaws with exceptional accuracy.
Using two probes positioned on opposite sides of a weld or component, TOFD measures the time it takes for ultrasonic sound waves to diffract from the tips of any defects present. This produces highly detailed cross-sectional images of the material’s internal structure, allowing for precise assessment of cracks, corrosion, and other discontinuities.
Renowned for its speed, accuracy, and reliability, TOFD is a preferred technique in industries such as oil and gas, power generation, and manufacturing, where safety and compliance are paramount.
