OBJECTIVE : To become familiar with NDT techniques and to get exposed to the concept and procedure associated with failure analysis.
Visual examination; liquid penetrant testing – procedure; penetrant testing materials, penetrant testing method – sensitivity; application and limitations; magnetic particle testing; definition and principle; magnetizing technique, procedure, equipment sensitivity and limitation; radiography – basic principle, electromagnetic radiation in film, radiographic imaging, inspection techniques, applications, limitations, real time radiography, safety in industrial radiography.
Eddy current testing – principle, instrument techniques, sensitivity application, limitation; ultrasonic testing – basic properties of sound beam, ultrasonic transducers, inspection methods, technique for normal beam inspection, flaw characterization technique, ultrasonic flaw detection equipment modes of display, immersion testing, advantage, limitations; acoustic emission testing – principles of AET and techniques.
Comparison and selection of NDT methods – defects like casting defects, forging and rolling defect, extrusion defect, drawing defect, grinding cracks, heat treating cracks, service defects; selection of NDT methods- VE, LPT, MPT, ECT, RT, UT, AET and thermography; selection of instrumentation for various NDT methods; reliability in NDT.
Failure analysis – methodology; approaches, tools and techniques of failure analysis; modes of failure; failure data retrieval; procedural steps for investigation of a failure for failure analysis.
Improvements (design, material) derived from failure analysis; two case studies; application of fracture mechanics concepts to design for safety.
