WHAT IS

NONDESTRUCTIVE TESTING ?

NONDESTRUCTIVE TESTING is defined as:Any method for examining an object or material in any

Tests Performed?

The purpose of the test may be to: detect internal or external flaws

measure geometric characteristics,

measure some of the objects or material's

ro erties

are there?

Today there are many different Nondestructive Testing

. , ,

Nondestructive Evaluation that are very widely known

and applied. These are:

Radiography

Visual

Ultrasonics

Liquid Penetrant

Can you tell me a little more about

what Nondestructive Evaluation is

used for ?

Increasingly, in our nuclear and space age, which someengineers have called the materials age,

o ma er a s per ec , u mus ave a equa e

properties to meet the increasingly rigorous demands

made upon it. NDT (as it is abbreviated) provides the means

to assure the detection or measurement of significant

properties or performance capabilities of materials,

, ,impairing their serviceability.

RT involves the use of enetratin X or amma

radiation to examine parts and products forimperfections. An X-ray machine or

radioactive isotope is used as a source of

radiation. Radiation is directed through a part. ,

shadowgraph is obtained that shows the

internal soundness of a art. Possible

imperfections show up as density changes in the

film, in much the same manner as a medical

radiograph can show broken bones.

MT is done by inducing a magnetic field in aferromagnetic material and dusting the surface

with iron particles (either dry or suspended in

a liquid). Surface imperfections will distort the

particles near such discontinuities, thus

ULTRASONICS

UT uses the transmission of high frequencysound waves into a material to detect

imperfections within the material, or changes

in material properties. The most commonly-

testing, wherein sound is introduced into the

to a receiver from internal imperfections or

from geometrical surfaces of the part.

LIQUID PENETRANT

PT is probably the most widely used NDT

method. The test object or material is coated

.

excess dye is removed from the surface, andthen a develo er is a lied. The develo er acts

like a blotter and draws penetrant out of

imperfections which are open to the surface.With visible dyes, the vivid color contrast

between the penetrant and the developer makes

e ee ou easy o see. uorescendyes, an ultraviolet lamp is used to make the

imperfections to be seen readily.
