Nondestructive testing has been defined as; applying a testing method to an object, part, component or system in order to evaluate it’s integrity without destroying the product’s future usefulness. Nondestructive inspection (NDI), nondestructive examination (NDE) or nondestructive testing (NDT) are terms generally used to identify the major inspection methods to perform evaluations or the application of the method to the item under inspection. Essentially, NDT is a function of material testing that evaluates a material or structure for uniformity, quality and serviceability and whether it will perform its intended function. In the beginning NDT was used primarily for process control and secondarily as quality control, subsequently the use of NDT became a means of meeting consumer demands for better products. It became a vital tool of modern engineering practice to achieve the required standards of quality in manufacturing which has instilled reputations in manufacturers adopting this methodology.
