Abstract
The evaluation of spot weldability is very important in managing the quality of products and also in increasing the credibility in the automotive manufacturing processes. The purpose of this study is to investigate the applicability of ultrasonic techniques for the evaluation of weldability in spot weldment. Through test results, it is confirmed that the behavior of the average attenuation coefficient (αavg) shows a close relationship with the behavior of tensile-shear strength. The transit time of the ultrasonic pulse echo and nugget size also show a close interrelation. If a larger experimental database with various welding conditions can he collected, then it can he shown that the attenuation coefficient and the transit time of an ultrasonic wave can be effective parameters in the evaluation of spot weldability.
