Abstract
A very good definition of defects position and dimension in welded joints is desirable for application of fracture mechanics techniques and improvement of industrial acceptability criteria. This paper illustrates the preliminary results obtained in the investigation of defects in aluminum welded joints at SYRMEP beamline of the Elettra synchrotron radiation facility in Trieste (Italy). The novel PHase Contrast (PHC) imaging technique consents a definition of the defects better than the one achievable with conventional welded joints control methods such as ultrasonic techniques, acoustic emission and radiography.File in questo prodotto:
