Non-destructive testing (NDT) contains a group of component testing methods for estimating the serviceability of a part without compromising its integrity. NDT is used generally in safety-critical industries such as oil and gas, offshore and marine, petrochemicals, aerospace, power generation and medical instruments and prostheses. 

Due to non-destructive inspection's (NDI) facility to ensure exceptionally high levels of safety and quality, NDT plays a significant role in both original equipment manufacturer and in-service maintenance.

Essentially all materials contain microscopic pores, vacancies and contaminants, which can be cast or projected into a material during primary manufacture or subsequent fabrication. These defects can extend when stressed, eventually leading to part failure. To know more about the Non-Destructive Testing, you can navigate to

Because the cost of part failure is exceptionally high in safety critical industries, it is of pre-eminent importance to detect flaws that effectively predict part failure before it actually happens. In principle, NDT attempts to discover flaws in a part's surface that predict future failure before the part fails in service and without compromising the part's utility.

Ultrasound and x-ray testing are competent of detecting defects both on the surface and throughout the body of a part. While both UT and X-ray are intelligent of detecting flaws in non-metallic parts, they both necessitate the use of cumbersome procedures and materials as well as hazardous waste disposal.
