FRICTION STIR SPOT WELDABILITY OF Al-Cu-Al MATERIAL COUPLE
(Gazi Univ, Fac Engineering Architecture, 2011) Kacar, R.; Emre, H. Ertek; Demir, H.; Guenduez, S.
Recently joining of metallic materials has gained a big importance. The problem can arise joining of advanced and new materials especially in industry. Thus, the solid state bonding methods have become much more popular effective in joining such materials. One of them is friction stir spot welding. In this study, 5754 quality aluminum couple using interlayer copper were joined by friction stir spot welding method using 1000 and 1600 rpm pin rotation for 3 and 5 second time intervals. The mechanical and metallurgical properties of weldment determined. The finding from this study compared with result that was obtained from FSSW Al-Al couple. The mechanical properties of FSSW welded Al-Cu-Al couple found better than Al-Al weldment.
