NDT ( NON DESTRUCTIVE TESTING )

NDT (NON DESTRUCTIVE  TESTING) :- 

Non Destructive Testing in great variety are in world  wide used to detect variations in structure,minute changes in surface finish, the presence of cracks or other physical discontinuities,measure  the thickness  of materials  and  coatings  and  to  determine other characteristics of industrial products.

NDT (MPI)
REASON'S FOR THE USE OF NDT:

"NDT" is used by the manufacturers for the following reasons: 
1. To ensure product reliability.
2. To make profit for the user.
a)   To ensure customer satisfaction
b)  To aid in better product reliability.
c)   To control the manufacturing processes.
d)  To lower the manufacturing costs.
e)   To maintain uniform quality level.

SOME OF THE MOST COMMON NDT METHODS ARE :
1.VISUAL  INSPECTION
2.LIQUID PENETRATION TEST
3.MAGNETIC PARTICLE TEST
4.RADIOGRAPHY  TEST
5.ULTRASONIC  TEST

Part -1 Most commonly asked Mechanical Interview Questions with answer

Most commonly asked Mechanical Interview Questions 1. What is the importance of the Thermodynamics in the field of Mechanical Engineering? All the mechanical engineering systems are studied with the help of thermodynamics. Hence it is very important for the mechanical engineers. 2. How many Laws of Thermodynamics are there? There are three laws of the thermodynamics. First Law : Energy can be neither created nor destroyed. It can only change forms.In any process in an isolated system, the total energy remains the same. Second Law : When two isolated systems in separate but nearby regions of space, each in thermodynamic equilibrium in itself, but not in equilibrium with each other at first, are at some time allowed to interact, breaking the isolation that separates the two systems, and they exchange matter or energy, they will eventually reach a mutual thermodynamic equilibrium. The sum of the entropy's of the initial, isolated systems is less than or equal to the entropy of the ...

'NICK' BREAK (BEND) TEST

'NICK' BREAK (BEND) TEST Object :  As for fillet weld fracture, used on butt welds. Method: The specimen is cut transversely to the weld, and a saw cut is applied along the center of the weld face. The best place for the cut is at a start I stop. The specimen is fractured by bending or by hammer blows. The nick bend test will find internal defects. Reporting Results: Thickness of material.  Width of specimen.  Location of fracture.  Appearance of joint after fracture.

DESTRUCTIVE TESTING

DESTRUCTIVE TESTING Destructive tests on raw materials, welded joints are usually made as part of the approval of material/ welding procedure or a welder. Commonly used destructive tests are: Hardness  Bend  Tensile Charpy Fracture tests Macro section TYPES OF TEST Quantitative (For measuring a 'quantity')  Tensile Charpy Hardness C.T.O.T. (crack tip opening test) Qualitative (For assessing joint 'quality') Bend test Nick break  Macro Fillet fracture The test pieces are cut from the test weld and their location is often specified in the standard. The areas for test are shown below.
