프루브 길이에 따른 A5052 겹치기 마찰교반접합 특성

다국어 초록 (Multilingual Abstract)

The Friction Stir Welding (FSW) has mainly been used for making butt joints in Al alloys. The development of Friction Stir Lap Welding (FSLW) would expand the number of applications. In this study, for effective application on thin aluminum alloy lap joint, non-heat treatment A5052 alloys were joined by FSLW with the length of probe 2.3 ㎜ and 3.0 ㎜. Investigating the characteristics of joint area showed the results were as below ; When the length of probe was 2.3 ㎜, good joint area was formed at all welding condition except for 600 rpm-700 ㎜/min. In the case of 3.0 ㎜ probe length, there was formed good joint area without defects at 1500 rpm-100 ㎜/min. The width of joint area, position and size of defects were very important factors for FSLW, due to heat input and stirring intensity.
