What is Nondestructive Testing?

Testing + Inspection

Nondestructive Testing (NDT) is a “health checkup” for materials, components, or entire systems, such as pipelines, bridges, aircraft

NDT is commonly used in forensic engineering, mechanical engineering, petroleum engineering, electrical engineering, civil engineering, systems engineering, aeronautical engineering, medicine, and art. In addition, it plays a key role in everyday life and is necessary to assure safety and reliability. Typical examples are the checks for structural integrity in the aviation industry, tests for welds on pressurized process vessels, and checks for safety in the nuclear industry.

The “health checkup” allows technicians to see problems, like cracks or other damage, that aren’t immediately visible.

The best part about NDT is that it doesn’t damage or destroy the things it’s testing. Think of it like getting an X-ray or an ultrasound at a hospital – you can see what’s happening inside your body without any cuts or surgery.

Nondestructive Testing (NDT), also known as Nondestructive Examination (NDE), is a wide group of analysis techniques used in science and technology to evaluate the properties of a material, component, or system without causing damage. Because NDT does not permanently alter the article being inspected, it is a highly valuable technique that can save both money and time in product evaluation, troubleshooting, and research.
