Non Destructive Testing

Frequently there is an urgent need to test a material or a part to know whether or not it meets design specifications or contains cracks, hard spots or any other flaw that may seriously affect the design and performance requirements. In this respect Non-Destructive Testing plays an important role, since it enables testing of a part without destroying it and still conclude whether the part is defective or not and whether there is a reasonable assurance that the part or product will be safe, when used in its intended application While measurements and inspection by gauges and various measuring instruments provide a quantitative information about the dimensions and tolerances, a qualitative information concerning the various flaws or defects is reading and easily made available by NDT at a reduced cost in the shop floor itself, so that corrective action can be taken immediately, so as to increase the reliability and quality of the product. Having realized the importance of NDT in the manufacturing and production, many universities in India have introduced a full-fledged course on NDT in Mechanical Engineering Curriculum.
