About NDT


About Nondestructive Testing

Definition

"Quality control method that does not damage or destroy the material or product being tested. Performed on a finished

item instead of on a material sample, it uses infrared radiation, radiography, ultrasound, x-rays, and other techniques to
detect fatigue effects, structural flaws, and other such defects. Used also in authentication of art objects and paintings."

So what is NDT?

Basically NDT is a nondestructive testing method performed on an object of any size, shape or type of material to then determine either the presence of, or the absence of discontinuities, which means that the material is inspected for
breaks, gaps, cracks, or interruptions in the flow of the material (or lack of the previously stated). NDT doesn't just
show something that is damaged, but also ensures quality in existing material (by inspection of said material) and proving
the lack of any discontinuities, thus one refers to non destructive testing as quality control.

Who uses NDT?

Anyone in the field of inspection of aircrafts, space shuttles, gas turbines, pipelines, power plants, chemical plants, refineries, hydroplants, motor vehicles, buildings, oil platforms, bridges and so on uses NDT as a method of quality
control, which then ensures the safety and reliability of each. Imagine a crack in a turbine that was built into an airplane
and the catastrophe, which can occur if this discontinuity was not found. During refueling outages, piping and turbines
have to be inspected so that the flow of power generation can continue without problems; NDT personnel ensure that
these problems do not take place.

NDT methods, each of them developed for specific purposes, ensure not only the safe use of the various inspected elements, but also ensure quality of the same.

Penetrant Testing (PT)

Image
Penetrant Testing (PT) In general terms, penetrant testing reveals surface discontinuities by the bleedout of a penetrating medium against a contrasting colored background. This is accomplished by applying a penetrant (usually liquid) to the cleaned surface of the test piece. Once this penetrant is allowed to remain on the surface for a prescribed time (dwell time), it will be drawn into any surface opening by capillary action. Subsequent removal of excess penetrant and application of a developer draws remaining penetrant from discontinuities.  The resultant indications are shown in high contrast and magnify the presence of the discontinuity so it can be visually interpreted. There are two primary ways in which penetrant materials are grouped: specifically, the type of indication produced, and the method of excess penetrant removal.  The two penetrant indications are visible and fluorescent.  The visible dye (usually red) produces a vivid red indication against

Magnetic Particle Testing (MT)

Magnetic Particle Testing (MT) This particular nondestructive test method is used primarily to discover surface discontinuities in ferromagnetic materials.  While indications can be observed from subsurface discontinuities very near the surface, they are very difficult to interpret, and often require testing by other methods.  Other NDE techniques are usually required for subsurface discontinuity detection and interpretation.  However, surface discontinuities present in a magnetized part will cause the applied magnetic field to create “poles” of opposite sign on either side of the discontinuity, creating a very attractive force for iron particles.  If iron particles, which are “magnetic particles” since they can become magnetized, are spnnkled on this surface, they will be held in place by this attractive field to produce an accumulation of iron particles and a visual indication of the discontinuity. While several different types of magnetic particle tests exist, th

Nondestructive Testing (NDT)

Nondestructive Testing (NDT) One of the purposes of an effective quality control program is to determine the suitability of a given base metal or a weld to perform its intended service. One way to judge that suitability is to subject the base metal or weld to destructive tests which would provide information about the performance of that test object. The major disadvantage of such an approach is that, as the name implies, the test object is destroyed in the process. Therefore, a number of tests have been developed to provide an indication of the acceptability of the test object without rendering it unusable for service. These various tests are referred to as nandestructìve tests, because they permit the nondestructive evaluation (NDE) of the metal or component. Even the destructive testing of a given percentage of parts can be expensive and assumes that the untested parts are of the same quality as those tested. Nondestructive tests yield indirect, yet still valid, results
