Fundamental Study of Lap Joint on FSW

마찰교반접합에 의한 겹치기 이음부의 기초적 연구

Development of FSW for use in lap joint production would expend the number of applications that could benefit from the technique. In the study, an extensive investigation was carried out on FSW lap joints, including interface morphology and mechanical properties. Welding variables included welding speed, rotation speed and, of particular importance, lap joint a methods. Examination of metallographic cross sections and failure locations showed a critical sheet interface present in all welds. Results indicates FSW lap joints may potentially replace other joining processes like resistance spot welding and riveting.
