BAXTER, MN — Nondestructive Testing (NDT) is one of the leading high demand jobs that is showing growth year over year. The American Institute of Nondestructive Testing is an NDT school located in Baxter, Minn., that has currently moved into a new 6,400 square-foot building.
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.
There is a broad spectrum of applications for portable helium leak detectors that touches numerous industry market segments. Vacuum systems as well as a wide variety of products and devices require leak testing as part of the quality testing process.
