Measuring the time of flight of the diffracted beams enables accurate and reliable flaw detection and sizing, even if the crack is off-oriented to the intial beam direction. When the beam comes in contact with the tip of aįlaw, or crack, diffracted energy is cast in all directions. TOFD provides a wide area of coverage with a single beam by exploiting ultrasonic beam spread theory inside the wedge and the inspected material. One sensor sends the ultrasonic beam into the material and the other sensor receives reflected and diffracted ultrasound from anomalies and geometric reflectors. Ultrasonic sensors are placed on each side of the weld. TOFD is usually performed using longitudinal waves as the primary detection method.
