Abstract
Capabilities of modern AUT means, developed in E.O. Paton Electric Welding Institute have been considered. It is shown that since the parameters characterizing the objects of diagnostics, defects, loading conditions and mechanical properties of the materials can vary in time, an integrated approach is effective, provided computerized systems are used.
Keywords: NDT, automatic UT, defectoscopy, technical diagnostics, computerized expert systems, integrated approach, residual life of pipelines
