Non Destructive Testing is also known as NDT or NDI. Non-Destructive testing is a very valuable technique or process which helps to evaluate the wholeness of the components or materials of an object. Through this testing the characteristics of an object is also determined. Non-Destructive is a very cost efficient group analysis technique. Testing includes research, component evaluation and solutions to the problems. Non-Destructive testing is more economically viable then other alternatives. NDT performs the testing without bringing any alteration, harm, or chance of destroying the object to be tested.
Magnetic Particle Testing is accomplished by inducing a magnetic field in a ferromagnetic material and then dusting the surface with iron ferrite particles. The surface will produce magnetic poles and distort the magnetic flux in such a way that the iron particles are attracted and concentrated to the indication making defects on the surface of the material visible.
