There are a variety of techniques for examining various articles that are very essential in the fields of science and technology such as the non-destructive examination (NDE) also referred to as non-destructive testing. It is through these examination techniques that one is able to evaluate and determine the various properties of materials being used, components as well as the systems available without causing any damage to them. The various fields of science and technology that makes use of these techniques include forensic, mechanical engineering, electrical engineering, petroleum engineering, civil engineering, medicine, aeronautical engineering, arts, systems engineering among many others. Some of the most common methods that are used in the non-destructive testing includes the magnetic-particle, eddy-current, radiographic, liquid penetrant, ultrasonic as well as visual testing.
These non-destructive examination methods usually rely on the use of sound, electromagnetic radiations and other signals that enhance conversion to test various articles such as metallic, non-metallic, artifacts, food products, infrastructures and antiquities for composition, integrity or condition without altering the article. These test equipment and tools used during the non-destructive testing need to be calibrated depending on what is being tested and the level of sensitivity being used. Calibration is done to enhance accuracy and precision of the testing equipment and it is usually done by the use of a calibration block also known as a reference block. The calibration is usually done depending on the application of the testing equipment as well as the shape and the form of the object to be evaluated.
The non-destructive evaluation makes use of various methods to help in locating the defect in the area of application as well as evaluating the shape, size as well as the orientation of the given defect. All over the world, there are a variety of companies that have specialized in the manufacture of various non-destructive examination equipment for use on various sectors such as the NDE flaw technology. One can do some online searches in various website to look for a suitable manufacturer of the non-destructive testing equipment that suits them for the intended purpose. One can also ask for referrals from people around who may have information regarding the equipment to get a suitable manufacturer where they can acquire the equipment needed.
Non-destructive testing techniques have been recommended for use in various sectors where the failure of a given component is likely to lead to some significant hazard or even some economic losses such as pressure vessels, transportation, piping, building structures as well as in hoisting equipment. Some of the most recommended applications of these equipment includes welding verification, structural mechanics, as well as in certain medical procedures such as endoscopy, radiography, and ultrasonic testing.
