How Should an NDT Process be Qualified?

Webinars 14 June 2021

In broad terms, the purpose of non-destructive testing (NDT) is to determine whether a component is acceptable for use or whether it is in some way defective. The purpose of inspection qualification is to provide assurance that an NDT system is itself fit for its purpose. But how should an inspection be qualified?

During this webinar, Charles Schneider will describe the historical background to the use of inspection qualification in the UK nuclear industry. He will review various approaches used to assess the reliability of an inspection, with a particular focus on flaw detection, and he will explain how these have arisen from different approaches to inspection qualification adopted within different jurisdictions and industry sectors. The webinar will outline the strengths and weaknesses of each approach and will discuss how the associated methods of analysis could be further refined and used to support inspection qualification in the future.

The application of these principles will be illustrated using examples from TWI’s own experience of inspection qualification.

Technology Fellow - NDT

Charles spent 11 years in the power generation industry, working mainly on the development of mathematical models for ultrasonic inspection. He joined TWI’s Structural Integrity Department in 1997. Since then he has continued to develop statistical models for the reliability of inspection techniques, including AUT of line pipe girth welds qualified to DNV standard OS-F101. He has led independent qualification bodies overseeing various types of inspection, including ultrasonic phased array testing of fillet welds for the nuclear sector. His publications cover various aspects of inspection modelling and reliability.
