NDT

Nondestructive testing, or NDT, encompasses a wide array of technologies and techniques used in manufacturing to inspect, test, and evaluate the properties of a material, components and entire products without causing damage. Due to the non-invasive nature, as well as the savings of time and money, NDT is a highly sought approach to quality control.

Take, for instance, weld inspection. Welds are commonly used to join two or more metal parts and these welds often encounter stress and fatigue over time. If these welds are not properly created and formed or have defects such as a poor bond or cracks on the inside of the weld not visible to the naked eye, they could fail. For reasons like this, NDT is used in some of the most safety-concerned industries, including transportation, aerospace, medical device, and medical imaging. Some common NDT methods and technologies include eddy-current, magnetic-particle inspection, liquid penetrant, radiography, and ultrasonic, just to name a few.
