Application with respect to product and Industries are practically unlimited. NDT Techniques can inspect a small pin to big dam structures. Some industries in which NDT plaus a key role include the following Aerospace, Aircraft, Automotive, Casting & Forging, Chemical & Petroleum, Construction, Electronics, Food Processing, Marine, Fabrication, Air port Security, Nuclear, Defence, Transportation and Utilities.

Advantages of NDT

• NDT tests are made directly upon the objects to be in service and hence there is no doubt that the tests were made on representative test objects.
• Tests can be made on every unit to be used in service (If Economically Justified); consequently they may be used validly even when great differences from unit to unit occur in production lots.
• Tests are made if desired on the entire production parts; consequently the evaluation applies to the part as a whole.
• Many Non Destructive tests, each sensitive to different properties of the material or part, may be applied simultaneously or sequentially to measure as many properties correlated with service performance as may be desired.
• NDT may be applied to parts in service often without interruption of service and with no loss of serviceable parts.
• Acceptable parts of very high fabrication costs are not lost in testing, consequently, extensive testing during service is possible.
• Little or no specimen preparation is required in many NDT tests. Several forms of NDT equipments are portable and are capable of rapid sorting and testing. The cost of NDT in most cases is far less than the cost of adequate Destructive tests except X-Ray inspection of low fabrication cost items.
• Most NDT methods are much more rapid and require far fewer man hours than typical Destructive tests and hence economical.
