Report of talk on “Non Destructive Testing Techniques”

The Dept of Mechanical Engineering of Don Bosco College of engineering organized a talk on “Non Destructive Testing Techniques” in association with Institution of Engineers, India on 14^th October 2017 for Second year Mechanical engineering students. The resource person was Mr. Subash Bandodkar, Retired DGM, Zuari Industries Ltd, Goa.

He explained the students that non-destructive testing (NDT) is the development and application of technical methods to examine material of components in ways that do not impair future usefulness and serviceability in order to detect, locate, measure  and evaluate discontinuities, and other imperfections, to assess integrity, properties and composition; and to measure geometrical and physical characteristics. He said that Non-destructive testing (NDT) plays an important role in the quality control not only of the finished products, but also of half finished products as well as the initial raw materials. NDT can be used at all stages of the production process. It can also be used during the process of establishing a new technology by product quality or when developing a new product.

He explained the different types of NDT methods and their applications in the industry. Some of the major NDT methods discussed were Magnetic Particle Testing (MT), Liquid Penetrant Testing (PT), Radiographic Testing (RT), Ultrasonic Testing (UT), Electromagnetic Testing (ET), Laser Testing Methods (LM), and Leak Testing (LT).

The talk was coordinated by Prof. Sharad Shanbhag and Prof. Manjunath Narvate.
