Quality in NDT – two approaches

Quality Assurance in NDT

The importance of Nondestructive Testing (NDT) as a Quality Control/ Quality Assurance tool in the industrial domain cannot be over-emphasized. With the rapid advancement in research and technology, the NDT field is becoming larger and more sophisticated day by day. Innovative research in materials science and digital technology is paving the way for more and more new methods in NDT technology....

Quality Control and NDT

Nonlinear Acoustic Ndt: Approaches, Methods, and Applications

Conventional acoustic instruments widely used in industry and technology for material characterisation and quality assessment make use of so-called linear acoustic response of materials that generally results in the amplitude and phase variations of the input signal. The nonlinear approach to acoustic NDT is concerned with non-linear material response, which is inherently related to the frequen...

EFNDT Guidelines on the overall NDT quality system in Europe

This paper describes a project in progress under the auspices of EFNDT Task Group 3 on Quality in NDT. The project was conceived as a result of the EFNDT strategic planning exercise in 2005-6. The objective is to prepare guidelines on achieving quality in NDT to help develop a better understanding by users and purchasers of NDT services of the roles of the various measures available for control...

Materials Characterization a Challange in Ndt for Quality Management

NDT is mainly discussed as an engineering technology to detect, classify and size material imperfections, called material defects. Lattice defects and microstructure inhomogeneities like vacancies, dissolved atoms dislocations and precipitations are normally not discussed as defects but they are influence parameters which mainly predict the macroscopic properties, the physical properties as wel...
