Abstract

In this study, a new technology based on the ultrasonic guided wave to inspect the weld part is presented. The characteristic of a guided wave to travel a long distance over a welded part provides an efficient inspection. This guided wave technique overcomes a tedious scanning procedure using a conventional bulk shear wave angle beam technique. A proper mode and frequency tuning process with knowledge of dispersion curves and wave structure profiles allows us to propose a promising alternative which makes it possible to alleviate such limitations encountered with the conventional technique. Some sample experimental data are also provided with a detailed guideline showing the utility of guided waves when using a proper mode selection for the weldment.
