Non Destructive Testing detail syllabus for Agricultural Technology (123), M scheme is taken from TNDTE official website and presented for diploma students. The course code (32671), and for exam duration, Teaching Hr/week, Practical Hr/week, Total Marks, internal marks, theory marks, duration and credits do visit complete sem subjects post given below.
For all other metallurgy 5th sem syllabus for diploma m scheme tndte you can visit Metallurgy 5th Sem Syllabus for Diploma M Scheme TNDTE Subjects. For all other ELECTIVE – I THEORY subjects do refer to ELECTIVE – I THEORY. The detail syllabus for non destructive testing is as follows.
Rationale:
Modern testing methods should be fast, accurate and highly reliable and which helps in predicting the soundness of parts made by various manufacturing processes. By doing this practical the students will be given the opportunities and confidence of handling various new and sophisticated instruments for ensuring the quality of the product/part manufactured.
Objectives:
At the end of the study of V Semester the student will be able to
- The subject provides advanced methods of testing the components without impairing the engineering utility of the components.
- Various methods and aids used for Visual inspection & Leak testing are discussed.
- Acquire knowledge about the principles and types of Liquid Penetrant tests to find surface defects.
- To impart knowledge about Magnetic Particle Inspection to locate surface and sub-surface defects.
- Testing the components using X-ray & Gamma rays will help the faster and accurate methods of NDT.
- Radiation safety and Monitoring will provide safe handling and maintenance with Radiography.
- The topic provides detection of minute flaws and measurement using Ultrasonic waves.
- Various techniques of scans& types are discussed to test the components using Ultrasonic waves.
- Advanced techniques like Eddy Current, Acoustic Emission & Thermography will be helpful in identifying defects like compositional mix-ups etc.
