Time of Flight Diffraction is an advanced ultrasonic inspection technique that is suitable for fast and reliable results. It is a technique which can simultaneously detect and size defects. TOFD inspection employs two longitudinal wave (L-wave) angle beam transducers arranged symmetrically opposite facing each other, whereby one probe acts like a transmitter of ultrasonic energy while the other probe receives the ultrasound energy. This inspection method is best suitable a wide range of applications such as inspection of piping and pressure vessels.  This technology complies with the requirements of various industry standards (ASME, API, DNV, EN-ISO)
