To get acquaintance with various non-destructive evaluation techniques commonly practiced in industries and research organizations / institutions.

To know the underlying principles behind the different non-destructive techniques such as Liquid Penetrant Testing / Examination (LPT), Magnetic Particle Inspection (MPI), Ultrasonic Testing / Inspection (UT), Eddy-Current Inspection (EC) and Radiography (RT).

To develop understanding of methodology, applications, advantages and limitations of various commonly used non-destructive evaluation techniques (LPT, MPI, UT, EC and RT).

To acquire the comprehensive theoretical knowledge about the procedure of NDE techniques as per certain standards and specification and prepare the students to qualify the theoretical course content of Level I and II of American Society for Non-Destructive Testing (ASNT) or Indian Society for Non-Destructive testing (ISNT) examinations, which are considered to be the job orientated certification courses.

The Course Outcomes (COs) are as follows:

CO1
Students will gain knowledge of the various NDE methods and their significance and specific applications, which are frequently used in industries and research institutions.

CO2
Students will be able to understand the significant non-destructive testing methods - Liquid Penetrant Testing (LPT) - that are employed to estimate the surface and sub-surface defects in metallic materials. Students will be familiar with the LPT techniques and associated fundamental physical principles, procedures, instruments, benefits, limitations, applicable materials, and standards. Students will be eligible to appear for the theoretical examinations of Level I and II courses in LPT of the ASNT or ISNT, which are considered job-oriented certification courses.

CO3
Students will get an understanding of the Magnetic Particle Inspection (MPI) technique used to assess the surface and sub-surface defects in ferrous (magnetic) metallic materials. The basic physical principles, procedures, tools, advantages, drawbacks, relevant materials, and standards of the MPI techniques will all be familiar to the students. Students will be ready and qualified to take the theoretical exams for the ASNT or ISNT's Level I and II MPI courses, which are regarded as career-focused certification programs.


CO4
Students will get an understanding of the method of detection and interpretation of surface, sub-surface, and internal defects in metallic materials using an important UT (ultrasonic testing) non-destructive testing approach. Students will be familiar with the fundamental physical ideas, procedures, tools and their calibration, benefits, limitations, reference flaws, and standards that support performing the UT test. Students will be competent and trained to take the theoretical exams for the ASNT or ISNT's Level I and II UT courses, which are regarded as job-oriented certification programs.

CO5
Students will gain knowledge of the eddy-current inspection (EC), which is used to evaluate surface and subsurface flaws in non-magnetic but conductive metallic materials. The students will be familiar with the fundamental physical concepts, procedures, instruments, benefits, limitations, pertinent resources of eddy current, and standards of the EC techniques. Students will be prepared and capable of passing the theoretical tests for the Level I and II EC courses offered by the ASNT or ISNT, which are recognized as career-focused certification programs.
