Course Objectives

Course Outcomes

The Course Outcomes are as follows: <br /> <br />CO1 <br />Students will get theoretical know-how about the various non-destructive evaluation techniques commonly practised in Indian industries and research organizations / institutions. <br /> <br />CO2 <br />Students will know the underlying physical 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). <br /> <br />CO3 <br />Students will develop understanding of methodology, applications, advantages and limitations of various commonly used non-destructive evaluation techniques (LPT, MPI, UT, EC and RT). <br /> <br />CO4 <br />Students will acquire the comprehensive theoretical knowledge about the procedure of NDE techniques as per certain standards and specification and will help in preparation for 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.
