NDT Career Development Tips

The success of any Nondestructive testing (NDT) methods and procedures depends upon the knowledge, skill, and experience of the NDT personnel involved in the profession. The person(s) responsible for detection, interpretation and evaluation of indications, such as Ultrasonic testing, Radiographic testing, or Magnetic particle testing, must be qualified and certified to specific industry or other acceptable government or industry standards such as American Society for Non destructive Testing (ASNT) Personnel Qualification and...

Snells Law, Refraction and Reflection

Like light, when an incident ultrasonic wave encounters an interface to an adjacent material of a different velocity, at an angle other than normal to the surface, then both reflected and refracted waves are produced.Understanding refraction and how ultrasonic energy is refracted is especially important when using angle probes or the immersion technique. It is also the foundation formula behind the calculations used to determine a materials first and second critical angles.First Critical AngleBefore the angle of incidence reaches...

Ultrasonic Test Equipment

The ultrasonic test equipment is used to provide information on the uniformity of concrete, cavities, cracks and defects. The ultrasonic test equipment is based on the pulse velocity method. It is recommended to measure the distance (path length) between the transducers as accurately as possible before the testing. The standard measuring procedure is:* Apply the couplant. It is very important to ensure adequate acoustic coupling of the transducers to the surface under test. A thin layer of couplant should be applied to the transducers...
