Ultrasonic Velocity Measurement
Ultrasonic velocity measurement using Ultrasonic Flaw detector is as simple as measuring the time it takes for a pulse of ultrasound to travel from one transducer to another (pitch-catch) or return to the same transducer (pulse-echo).
Changes in ultrasonic wave propagation speed, along with energy losses, from interactions with materials microstructures are often used to nondestructively gain information about a material's properties. Measurements of sound velocity and ultrasonic wave attenuation can be related to the elastic properties that can be used to characterize the texture of polycrystalline metals. These measurements enable industry to replace destructive microscopic inspections with nondestructive methods.
