The history of X-rays goes back to 1895, when Wilhelm Conrad Roentgen discovered and identified X-rays. Then, in 1909, Charles Glover Barkla discovered a connection between X-rays radiating from a sample and the atomic weight of the sample.
A Q&A with lead Frost & Sullivan Principle Lead Nikhil Jain on how NDT training services are shifting to fit a manufacturing landscape that is being reshaped by changes in industry, economy and technology.
Despite changing market dynamics, the nondestructive testing (NDT) industry continues to grow and innovate with an influx of new technologies, and as a result, the NDT job market has cracked wide open. However, the meeting of NDT technician supply with demand, whether it is too much of a demand or not enough, has been a consistent issue.
Nondestructive testing (NDT) provides the ability to monitor various aspects of material and product quality without compromising part integrity. Many NDT technologies can be applied to ensure proper manufacturing and functionality.
Precisely measuring and validating parts made from low-density materials such as plastic can be tricky and time-consuming. For example, silicone parts readily bend and flex, leading to inaccuracies. Fixturing, the traditional solution to immobilize and align parts for measurement, is a lengthy process involving engineering, construction and validation of the custom fixture.
This method has been proven to be one of the most reliable NDT methods for the detection of surface and near-surface discontinuities, as mentioned in an article “Key Elements of Magnetic Particle Testing” in the August 2015 issue of Quality. And even though it is a time-proven and accepted method, there are still cases of misuse and a general lack of understanding of the basic MT principles.
