It is a very broad, interdisciplinary filed that plays a critical role in assuring that structural components and system perform their function in reliable and cost effective fashion. NDT technicians and engineers define and implement tests that locate and characterize material conditions and flaws that might otherwise cause planes to crash. Reactors to fail, trains to derail, pipelines to burst, and a variety of less visible, but equally troubling events. These tests are performed in a manner that does not affect the future usefulness of the object or material. Generally speaking, NDT applies to industrial inspections. The technologies that are used in NDT are similar to those used in the medical industry, but nonliving objects are the subjects of the inspections.
Non-destructive evaluation (NDE) is a term that is often used interchangeably with NDT. However technically, NDE is used to describe measurements that are more quantitative in nature. For example, and NDE method would not only locate a defect, but it would also be used to measure something about that defect such as its size, shape, and orientation. NDE may be used to determine material properties, such as fracture toughness, formability, and other physical characteristics.
Non Destructive Testing Methods
Many people are already familiar with some of the technologies that are used in NDT and NDE from their uses in the medical industry. Most people have also had an X-ray taken and many mothers have had ultrasound used by doctors to give their baby checkups while still in the womb. The number of methods seems to grow daily, most commonly used methods is provided below.
Radiography Testing
Ultyrasocne Testing
Penetrant Testing
Magnetic Testing
