Advances in applications of non-destructive testing (NDT): a review

Manufacturing defects and discontinuities in a product are anomalies which can lead to severe damages may sometimes involve loss of life. These must be examined corrected before the goes into service. There two methods testing for viz. Destructive Testing Non-Destructive Testing. entails subjecting conditions that leads failure whereas (NDT) is process examining products way it retains its usefulness future This paper discusses various involved NDT such as Visual Testing, Magnetic Particle Inspection, Penetrant Ultrasonic Radiographic Acoustic Emission Eddy Current with major focus on advances applications NDT.
