What Does TOFD Stand For?

TOFD stands for Time Of Flight Diffraction

Time of Flight Diffraction (TOFD) is a non-destructive testing technique used in the field of ultrasonic testing to detect and size flaws in materials. By analyzing the time it takes for ultrasonic waves to travel to a defect and back, TOFD provides detailed information about the nature and extent of imperfections, such as cracks or voids, within a structure. This method is particularly effective for thick materials and is widely utilized in industries such as aerospace, oil and gas, and manufacturing, ensuring the integrity and safety of critical components.
