Non-Destructive Testing:
 Is a Industry which deals with critical engineered materials and  uses a series of test methods and techniques
 designed to detect internal or external discontinuities or flaws without physical damage to the part under test.


The reason for Nondestructive Testing:

 Product Reliability

 Accident Prevention

 Product Design Improvement


 Maintain Uniform Quality Standards



The most commonly used methods are:


Visual Testing:
 Process: To inspect the surface of the material for any indications of a discontinuity or interruption

 in the normal surface configuration.

 Dimensional measuring and optical aid tools may be used.

 Advantages: To make the best judgment for the method and technique used.

 Limitations: Surface inspection only. Difficult to find small cracks.


Liquid Penetrant Testing:

 Process: Apply a penetrating liquid to the test material surface, Remove, Dry, Develop and then Inspect part.

 Advantages: A wide variety of materials can be tested. Inspection is simple, fast and relatively economical.

 Limitations: Surface flaw detection only. Part surface requires a thorough cleaning or etching.


Magnetic Particle Testing:

 Process: Magnetize part and apply iron oxide particles to the part surface.

 Flaws will attract particles giving an indication of the location of the flaws.

 Advantage: Surface and near subsurface flaw detection potential and linear indication sensitivity.

 Limitations: Method is restricted to a select group of ferromagnetic test materials only.


Radiography Testing:

 Process: Pass ionizing radiation through an object onto some recording media (Generally film)

 Advantages: Permanent visual record of the objects internal structure.

 Limitations: Part geometry, Safety hazard and Expense.


Ultrasonic Testing:

 Process: Transmit high frequency sound waves vibrations into the test material,

 Sound reflections caused by flaws produce displayed signals.

 Advantages: Surface and deep subsurface flaw location detection capabilities.

 Limitations: Part geometry, flaw orientation.


Electromagnetic Testing:

 Process: Eddy currents are produced by exposing conductive materials to an alternating magnetic field.

 Advantages: Flaw / Crack detection; conductivity measurements and sorting of

 mass or dimensional changes can be detected.

 Limitation: Operator variables; Depth of penetration of eddy currents.
