Current NDT test methods include: Acoustic Emission Testing (AE) This is a passive NDT technique, which relies on detecting the short bursts of ultrasound emitted by active cracks under a load. Sensors dispersed over the surface the structure detect the AE. It is even possible to detect AE fr...
Non-destructive testing (NDT) is exactly what its name implies— testing without destroying. More specifically, a non-destructive test is an examination of an object or material in any manner that will not impair its future usefulness. The major tools of NDT are radiography, ultrasonic,dye ...
The main application of a C-scan or XRD scan in an NDT process is to analyze cracks that are not visible to the naked eye. It finds cracks on welds and can also locate them inside components such as engine blocks, cylinder heads, valves, etc. ...

NDT-RAM is Resonant Inspection...
The primary advantage of NDT is that it does not destroy the test article, allowing for repeated testing or continued use after inspection. This saves money when test articles are expensive. NDT is particularly important in applications where even minor defects can have catastrophic consequences. How...
Train axles failures have caused major loss of life, with a consequential increase in both non-destructive testing (NDT) and manual inspection that is expensive and disruptive to efficient rolling stock maintenance. TWI plays a key role in an InnovateUK project, aiming to use complimentary methods...
NDE technology refers to an array of non destructive techniques (NDT) and processes to monitor, probe and measure material response. The measured response is related to a desired material property or test object attribute by interpretation. The main NDT methods are: Visual inspection....

Nanotomography (nano-CT) is similar to micro-CT and medical CT scanning but at resolutions in nanometers instead of microns or mm. Nano-CT uses a nano-focus X-ray source to capture 2D images during a 180 or 360 degree rotation of a sample. Advanced software is then used to turn those...
Pressure tests (both hydrostatic and pneumatic)must always be performed under controlled conditions, following an approved test plan, and documented in a test record. A single approved test plan could be used for several similar tests, but for each test, a separate test record is required. ...
