Nondestructive evaluation techniques play a major role in assuring the quality and uniformity of manufactured goods. NDE methods are also employed extensively in industry to assess the integrity and fitness-for-use of critical components. Modern engineering practice frequently require components to be designed in a manner that allows inspectability of the past during service.
The globalization of the world economy has raised the "bar" with respect to the quality of manufactured goods. NDE techniques are used as a process control tool to maintain uniformity and ensuring that the finished product meets requisite quality standards. Safety considerations as well as the desire to contain costs associated with catastrophic failure of engineering structures have contributed to the increase in the use of NDE techniques for evaluating the integrity of components in a number of industries including aerospace, automotive, defense, ordnance, surface transport, petrochemical and energy related industries.
