NDT stand for non-destructive testing. In other words it is a way of testing without destroying. This means that component the casting, weld or forming, can continue to be used and that the nondestructive testing method has done no harm.
In today's world where new materials are being developed, older materials and bounding methods are being subjected to higher pressures and loads, NDT ensures that materials can continue to operate to NDT can be used to ensure the quality right from raw material stage through fabrication and processing to pre-services and in service inspection.
Apart from enring the structural integrity, quality and reliability of components and plants, today NDT finds extensive application for condition monitoring, residual life assessment, energy audit,
