Non-destructive testing (NDT) at TWI

Nondestructive testing or Non-destructive testing (NDT) is a wide group of analysis techniques used in industry to evaluate the properties of a material, component or system without causing damage. The terms Nondestructive examination (NDE), Nondestructive inspection (NDI), and Nondestructive evaluation (NDE) are also commonly used to describe this technology.

Industry has an ongoing need for these technologies and techniques that can accurately locate, quantify, characterise and size flaws in a wide variety of materials, components and structures, and TWI has an undoubted and proven track record in the research, development and application of NDT and supporting technologies.

With every technology in use, industry has a responsibility to employ trained, competent and qualified staff to operate NDT technologies in order to use them safely and accurately. In many industrial sectors qualification and recognised certification is enforced by law or by the associated applied codes and standards. Recognising this, and using its expertise in having driven major developments within the NDT field, TWI has been best placed to design and develop its comprehensive programme of related NDT training, covering Conventional NDT courses and Advanced NDT courses.

TWI runs an NDT training programme designed to introduce newcomers to the most commonly used means of non-destructive testing. TWI has been at the forefront of inspection and non-destructive testing (NDT) of fabricated structures for more than 40 years. The NDT Technology Section is a multi-disciplinary group of over 60 engineers, consultants and technicians dedicated to the development and successful implementation of the full spectrum of NDT technologies.
