Non-destructive testing of welded fatigue specimens

Non Destructive Testing of Laser Welded Lap Seams by Eddy Current Technique

Eddy current method has been tested for detection and classification of defects in laser welded seams. Influence of disturbance effects was investigated systematically. Before analysis data have been processed for consideration of changes in material properties. It can be shown that seam different defects lead to different characteristic indication ranges in the impedance plane. By investigatio...

Non-Destructive Testing

This book consists of a collection of 27 articles dealing with the subject of probabilistic engineering mechanics with special emphasis on the ensuing computational issues. The book has two parts. The first part is meant as a tutorial on the basic aspects of probabilistic mechanics, whereas the second part is an overview of some of the applications that rely on probabilistic concepts for their ...

Non-destructive Testing

This section contains a review of physical fundamentals and results of practical implementation of methods of nondestructive testing (NDT) and evaluation. It also presents relevant information on magnetic, electrical, eddy current, HF electromagnetic, infrared, optical, acoustic, radiographic, penetrant and other (such as vibration, leakage testing and integrated) methods of NDT and evaluation ...

Non-destructive Testing: Neutron Radiography

The Hellenic Society of Non-destructive Testing

The liquid penetrant testing, and its capillary variety, and control of airtightness, are based on the filling by the liquid defectoscopic substances of capillaries and capillary-porous bodies. Physicomechanical interaction on the boundary liquid solid body influences seriously the eventual result of control. For the first time we investigated phenomena, as interaction in the capillary of two c...
