- Abstract
Ultrasonic bonding is relatively new and very useful technique for bonding dissimilar metals in which brittle intermetallic compounds are easily developed in conventional fusion welding processes The possibility of evaluations of ultrasonic bonds by ultrasonic testing was discussed in detail. In order to evaluate the quality of bonds it is necessary to obtain the correlation between the results by ultrasonic testing as non destructive test and mechanical properties, tensile shear strength in this work as a destructive test. It was confirmed that ultrasonic testing (C-scope mode) was useful to evaluate the bonding situations of the bonds by ultrasonic bonding when the appropriate threshold level was selected. In this study it was found that the threshold level of 200 had a good correlation between the result of ultrasonic testing and a tensile shear test.
