What Is Nondestructive Testing?

Nondestructive testing (NDT) RAPID , is a profession that blends quality assurance and materials science. NDT is used to inspect and evaluate materials, components, or assemblies without destroying their serviceability. Through a set of test methods, technicians identify cracks, voids, inclusions, and weld discontinuities, as well as identify misassembled subcomponents.

NDT is used to ensure product integrity and reliability, control manufacturing processes, lower production costs, and maintain a uniform quality level. Without it, the safety and reliability of components can be seriously jeopardized. This makes NDT crucial to help prevent catastrophic failures such as airplane and locomotive crashes, pipeline leaks and explosions, nuclear reactor failures, and ships sinking.

Industries that utilize NDT include:

Aerospace Manufacturing Energy (oil and gas, nuclear) Chemical Infrastructure (Bridges, Highways, Buildings) Transportation (Automotive, Railways) Maritime Construction

X-ray and Gamma Ray

X-rays and gamma rays can come from natural sources, such as radon gas, radioactive elements in the earth, and cosmic rays that hit the earth from outer space. But this type of radiation can also be man-made. X-rays and gamma rays are created in nuclear power plants, and are also used in smaller amounts for things like medical imaging tests, cancer treatment, and food irradiation.

X-rays and gamma rays are in packets of energy known as photons. Because X-rays and gamma rays have the same properties and health effects, they are grouped together here..

Both x-rays and gamma rays are forms of high-frequency (high-energy) ionizing radiation, which means they have enough energy to remove an electron from (ionize) an atom or molecule. Ionizing radiation can damage the DNA (genes) inside a cell. Sometimes this can lead to cancer later on.

Gamma rays and x-rays aren’t the only kinds of ionizing radiation. Some higher energy ultraviolet (UV) rays are also ionizing. Ionizing radiation can also exist in particle form, such as protons, neutrons, and alpha and beta particles.

Ultrasonic Test

Ultrasonic testing methods use sound waves to find defects and measure thickness.
Ultrasonic Testing (UT) is also often called Ultrasonic Thickness Measurement (UTM), Ultrasonic Thickness Testing (UTT), or Sonic Testing (ST). It is most commonly used on metal, because metal conducts sound waves in a manner that supports this kind of measurement.

This method is commonly used by inspectors as one of many Non-Destructive Testing (NDT) testing methods, allowing them to collect information about the condition of an asset without having to damage it.

[Ultrasonic testing is just one of the non-destructive testing (NDT) methods that inspectors use.

Dye Penetrant Test

Dye Penetrant Inspection (DPI) is widely used to detect surface breaking flaws..

This non-destructive testing technique, also known as liquid penetrant inspection (LPI), is a cost-effective method used to locate surface breaking flaws such as cracks, porosity, laps, seams and other surface discontinuities. . Dye penetrant inspection can be applied to both ferrous and non-ferrous materials and all non-porous materials (metals, plastics or ceramics).

The method is also useful for testing on-site as it is portable, and when applying certain techniques such as visible colour contrast there is no need for additional resources such as electricity or water. This makes it a highly convenient for inspecting surface discontinuities.

Heat Treatment

Heat treating (or heat treatment) is a group of industrial , thermal and metalworking processes used to alter the physical , and sometimes chemical, properties of a material. The most common application is metallurgical . Heat treatments are also used in the manufacture of many other materials, such as glass .

Heat treatment involves the use of heating or chilling, normally to extreme temperatures, to achieve the desired result such as hardening or softening of a material. Heat treatment techniques include annealing, case hardening, precipitation strengthening, tempering, carburizing, normalizing and quenching . Although the term heat treatment applies only to processes where the heating and cooling are done for the specific purpose of altering properties intentionally, heating and cooling often occur incidentally during other manufacturing processes such as hot forming or welding.

Advanced NDT Systems

Advanced non-destructive testing (ANDT) comprises a wide range of NDT techniques based on innovative technologies to inspect and analyze anomalies in assets with less disruption to operations. Compared with conventional NDT, it provides quicker results and improves accuracy while being cost-effective.

The establishment of Applus+ RTD itself was an innovation in 1937. At the time, it was the first non-governmental organization worldwide to provide commercial NDT services. Since then, Applus+ has developed several ANDT-patented methods, technologies, applications, and inspection procedures. Our Research & Development department, known as the Technology Centre, works closely with clients to convert challenges into innovative and customized solutions.
