What is NDT?
NDT stands for non-destructive testing. In other words it is a way of testing without destroying. This means that the component – the casting, weld or forging, 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 bonding methods are being subjected to higher pressures and loads, NDT ensures that materials can continue to operate to their highest capacity with the assurance that they will not fail within predetermined time limits. NDT can be used to ensure the quality right from raw the material stage through fabrication and processing to pre-service and in-service inspection.
Apart from ensuring the structural integrity, quality and reliability of components and plants, today NDT finds extensive applications for condition monitoring, residual life assessment, energy audit, etc.
