What is NDT?

“A Quality Conformance Test That Does Not Eliminate The Future Usage Of The Product Or Service Being Tested.”

“In nondestructive testing, tests are carried out in such a way as to not disturb the specimens structural or surface integrity. This type of testing is valuable because the specimen is not destroyed, however, these techniques generally require greater operator skill and the results are not always straightforward to interpret.”

 


Nondestructive testing (also called NDT, nondestructive evaluation, NDE, and nondestructive inspection, NDI) is testing that does not destroy the test object. NDE is vital for constructing and maintaining all types of components and structures. To detect different defects such as cracking and corrosion, there are different methods of testing available, such as X-ray (where cracks show up on the film) and ultrasound (where cracks show up as an echo blip on the screen). This article is aimed mainly at industrial NDT, but many of the methods described here can be used to test the human body. In fact methods from the medical field, where there tends to be more development funding available, have often been adapted for industrial use, as was the case with Digital Radiography.

While destructive testing usually provides a more reliable assessment of the state of the test object, destruction of the test object usually makes this type of test more costly to the test object's owner than nondestructive testing. Destructive testing is also inappropriate in many circumstances, such as forensic investigation. That there is a tradeoff between the cost of the test and its reliability favors a strategy in which most test objects are inspected nondestructively; destructive testing is performed on a sampling of test objects that is drawn randomly for the purpose of characterizing the testing reliability of the nondestructive test.

The Need For NDT

It is actually very difficult to weld or mold a solid object that has no risk of breaking in service, so testing at manufacture and during use is often essential. During the process of molding a metal object, for example, the metal may shrink as it cools, and crack or introduce voids inside the structure. Even the best welders (and welding machines) don't make 100% perfect welds. Some typical weld defects that need to be found and repaired are lack of fusion of the weld to the metal and porous bubbles inside the weld, both of which could cause a structure to break or a pipeline to rupture.
During their service lives, many industrial components need regular nondestructive tests to detect damage that may be difficult or expensive to find by everyday methods. For example:

  • • aircraft skins need regular checking to detect cracks;
  • • underground pipelines are subject to corrosion and stress corrosion cracking;
  • • pipes in industrial plants may be subject to erosion and corrosion from the products they carry;
  • • concrete structures may be weakened if the inner reinforcing steel is corroded;
  • pressure vessels may develop cracks in welds; the wire ropes in suspension bridges are subject to weather, vibration, and high loads, so testing for broken wires and other damage is important.

Over the past centuries, swordsmiths, blacksmiths, and bell-makers would listen to the ring of the objects they were creating to get an indication of the soundness of the material — a function that is now carried out by instrumentation and referred to as acoustic emission.
