Non destructive Evaluation (NDE) Techniques

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:

Although each method is dependent on different basic principles in both application and output, repeatable and reproducible NDE results depend on specific understanding and control of the:

No NDE process or procedure produces absolute discrimination of anomalies but the end output of a procedure may be quantified and the anomaly or flaw detection capability may be measured, analyzed, quantified and documented.
