Nondestructive Testing

Nondestructive testing (NDT) is actually a very broad field of multiple disciplines that is used to test, evaluate and inspect materials and various components for suspected damage or defects like discontinuities or differences that may affect the performance or safety or the specified material. It is very important for testing materials that would take time to take apart for checking and would prove to be a costly endeavor. It is NDT testing that allow engineers to see if bridges need repairing or if a plane is in the condition to fly. Without NDT it would be hard to know the flaws that are inside the plane without taking it apart, and in the airline business time is of essence. It is also used to test reactors, trains, pipelines and other …show more content…
NDT is an excellent quality control tool and ensures cost-effective, but definite and exact results ("Introduction to Nondestructive Testing", 2016). While generally used for checking industrial materials, Nondestructive evaluation (NDE) is a kind of NDT and is actually sometimes used interchangeably with the term, but NDE has its distinct difference -- it is mainly used to check for a defects shape, orientation, size and location within the human body. NDE in the medical field involves radiation, with its most common examples being the x-ray and the magnetic resonance imaging (MRI) testing ("About NDT", 2016). The importance of NDT/E is such that its testers have to always remain vigilant and have to be trained …show more content…
Also, radiologists need specific licenses to conduct their work, and it is actually very common for a radiologist to study for their tests in the same way that doctors and nurses study for theirs. Their examination is no joke, and (depending on the country) if the examinee fails they would have to wait until the next exam, which is usually after half a year or a year after their test date. Most NDT training and certification programs on the other hand are programs that are "based on the American Society for Nondestructive Testing (ASNT) Recommended Practice No. (Birring, Samy, & Rowland, 2011)" (Birring, Samy, & Rowland, 2011). While the training normally happens in colleges or the technicians ' employers, it is a must that the training be very good as bad training would result to weak technicians that would not be able to perform their tasks optimally. The NDT training and certification programs, which are based on the aforementioned SNT-TC-1A from the ASNT, provides guidelines for any person related to NDT methods. There are multiple standards that a training program must adhere to, which are: (1) a training program should meet the minimum required hours by the SNT-TC-1A, which can only change depending on the kind of certification that the employers
