What is Non-Destructive Testing (NDT)?

By definition, Non Destructive Testing is the testing of materials for surface or internal flaws or metallurgical condition, without interfering with the integrity of the material or suitability for service. The technique can be applied on a sampling basis for individual investigation or may be used for complete checking of material in a production quality system. 

What is the difference between Non Destructive Testing and Destructive Testing?

Destructive Testing destroys or changes the material in some way such that even if it passes the test, it is no longer fit for services. Examples might be tensile and compression testing. Non Destructive Testing (NDT) does not destroy or change the material so that it remains still fit for service if it passes the test.

Non Destructive Testing (NDT) Methods

Magnetic Particle Inspection NDT MPI NDT 2

Magnetic Particle Inspection MPI NDT

MPI is also known as Magnetic Particle Inspection. This method of Non Destructive Testing is used to detect surface and sub-surface discontinuities in ferromagnetic materials.

MPI can typically be used for the examination of welds, castings, forgings, and final machined components on new or existing equipment and structures. MPI NDT uses finely divided ferromagnetic particles to identify the location, size, and shape of the discontinuity. 

Dye Penetrant Testing NDT 2

Dye Penetrant NDT

Dye Penetrant NDT is used to detect surface breaking defects in both ferrous and non-ferrous materials. Dye Penetrant testing examines the surface of an item for surface breaking defects, such as cracks. Liquid penetrant is applied to the surface and left to soak, being drawn into any cracks by capillary action. Excess Dye Penetrant is then removed and a developer is applied to draw out the penetrant from cracks, which allows a visual inspection of any defects to be carried out.

Ultrasonic NDT

Ultrasonic NDT

Ultrasonic testing uses sound waves to identify and evaluate internal flaws. Typically used to assess weld penetration, fusion of boiler welds and any welded components in areas where visual inspection is not possible. used for complete checking of material in a production quality system.
