Conventional and Advanced Non-Destructive Test Techniques for Evaluation of Welds

Abstract

Non-destructive Testing (NDT) is an integral and the most important constituent of the Quality Assurance (QA) programme of any industry. The objectives of the QA programmes are safety, reliability and economy. Non-destructive evaluation (NDE) places due emphasis on characterisation of material including quantitative determination of the size, shape and location of a defect or anomaly thus enabling evaluation of structural integrity of a component.
