Main concept and aim of non-destructive testing of materials as applied to the inspection of the integrity of different joints and structures. The course provides the theoretical principles of conventional NDT methods and their capabilities and limitations. It also gives an introduction to different NDT techniques: visual, dye penetrate, magnetic particle, ultrasonic, radiographic, and Eddy Current methods. Application of NDT to inspection of joints, quality process control, and accept/reject criteria is emphasized. The practical sessions of this course include hands-on experiments by students for different NDT techniques. The associated laboratory session is designed to demonstrate calibration procedures, perform inspection techniques, and interpret the indications received from different discontinuities.
