In particular, Ultrasonic Testing (UT) is demanding because of the distortion of sound beam due to the anisotropic inhomogeneous material. For this reason, Radiographic Testing (RT) has been...
11 lut 2023 · Distance Calculation: The distance from the transducer to the reflector can be calculated using the formula: Distance (d) = TOF (t) * Velocity of sound (c) / 2. Example: An ultrasonic pulse with a velocity of 5900 m/s in steel and a time of flight of 20 microseconds. To calculate the distance to a reflector, we can use the following formula:
Skip distance calculation: (Abbreviations: HSD – Half Skip Distance, FSD – Full Skip Distance) Tan Ø = Perpendicular (BG)/ Base (AG) = AC (or HSD)/THK
15 gru 2021 · Using the refracted angle, beam index point and material thickness, the V‐path and skip distance of the sound beam is found. Once they have been calculated, the inspector can identify the transducer locations on the surface of the material corresponding to the crown, sidewall, and root of the weld.

To calculate values easily in your head, replace or round up the compression velocity from 5960000mm per second in steel to 6 kilometres per second, and transpose 4,000,000 cycles per second, for example, to 4 MHz.
ULTRASONIC TESTING (UT) USEFUL FORMULAE 1. Velocity of Ultrasonic Waves in a medium (V) = f x l OR Where f = Number of cycles per second is called frequency. Measured in ‘Hertz’. Abbreviated as ‘Hz’. One Hertz is equivalent to One cycle per second l = Distance covered in one cycle is wavelength
