Abstract

This study aimed not only to develop the optimization of dissimilar friction welding of pinion gear of a motor vehicle steels of SCM415 and SMn443, but also to develop the application technique of the acoustic emission to accomplish an in-process real-time quality(such as strength and toughness) evaluation during friction welding of the pinion gear by the AE technique.
