Definition - What does Nondestructive Testing mean?
Nondestructive Testing is an approach used for evaluating the properties of material without causing damage. It one of the most valuable techniques that can save time and money during product evaluation, research and trouble shooting. With the technological advancements, there are a number of methods that can be used for testing such as magnetic-particle, liquid penetrant, radiographic and low coherence interferometry. These methods rely upon sound, radiations and other inherent properties of materials. Nondestructive Testing is also used on ferrous materials from which iron particles are separated from dry dust even in highly magnetized states.
Petropedia explains Nondestructive Testing
Nondestructive Testing covers a broad range of industrial activities which include complete examination of equipment and assets so as to detect defects before any severe damage. It is essential to undergo the testing procedure as it improves the reliability and integrity of the processes. The process is examined by certified and well-trained inspectors. Nondestructive Testing is mainly used for weld verification, structure mechanics and as radiography in medicines. Being diving into several techniques and methods, it is important to choose a viable method to have high performance of equipment. Some commonly used methods are acoustic emission testing, blue etch anodize and liquid penetrant testing.
