NDT vs NDE, What is the difference?
NDT (non-destructive testing) and NDE (non-destructive evaluation) are both methods of examining materials or structures without causing any damage to them. While the terms are often used interchangeably, there are some subtle differences between the two.
NDT refers to a group of testing methods that are used to evaluate the properties of a material or component without altering its condition or structure. This is done by using various techniques to examine the material’s surface or internal structure, such as visual inspection, ultrasonic testing, or dye penetrant inspection.
NDE, on the other hand, is a broader term that refers to any method of evaluating the condition of a material or component without causing any damage to it. This includes not only NDT methods, but also other techniques such as thermal imaging, eddy current testing, and radiographic testing.
Overall, the main difference between NDT and NDE is that NDE is a broader term that includes a wider range of techniques for evaluating the condition of materials or structures, while NDT specifically refers to a group of testing methods that are used to examine the properties of a material or component.

Great explanation of the differences between NDT and NDE!
NDT focuses on identifying surface and subsurface flaws through specific testing methods, often geared toward finding defects that might impact performance or safety. NDE, however, takes this further by assessing a material’s overall integrity and serviceability, often incorporating NDT methods as part of a more comprehensive evaluation.
In practical applications, NDT might be the approach during manufacturing to ensure a product meets quality standards, while NDE might be employed throughout a component’s life to assess its condition and predict its remaining service life…
