Conventional Non-Destructive Testing Frequently used NDT methods Radiography Testing (RT) Detects and evaluates wall loss and weld defects Radiography uses gamma rays or X-rays to produce an image of an object on film or on a digital detector. Images are analyzed to detect wall loss, size pipes and plate, and to identify defects in welds, forgings, and castings during the manufacturing process

Destructive testing is an essential part of ensuring the integrity and performance of the welds used to manufacture everything from cars, planes, and ships to bridges, buildings, and pipelines. Destructive testing methods are also used for applications such as welding procedure qualification, welder performance qualification testing, and
The inspection of welding has progressed over the years with some innovative and sophisticated techniques being developed by welding engineers. These methods are all classed as non-destructive testing (NDT) and include radiography where the weld is x-rayed. The use of ultrasonics, magnets and dye penetration techniques also enables the welding of both ferrous and non ferrous metals to be
In destructive testing (or destructive physical analysis, DPA) tests are carried out to the specimen’s failure, in order to understand a specimen’s performance or material behavior under different loads.These tests are generally much easier to carry out, yield more information, and are easier to interpret than nondestructive testing.Destructive testing is most suitable, and economic, for
Non-Destructive Testing (NDT) – Guidance Document: An Introduction to NDT Common Methods 4 2.1.4 Operator It is of great importance that the operator has had sufficient training and experience before performing visual inspection.
