자동차용 피니온 기어재의 이종재 마찰용접과 실시간 AE평가

Dissimilar Friction Welding for Pinion Gear and Its Real Time AE Evaluation

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.
