Bu çalışmada, 6061 T6 alüminyum alaşımlarının katı hal kaynak yöntemlerinden biri olan tekrar doldurmalı sürtünme karıştırma nokta kaynağı (TSKNK) ile birleştirilebilmesi araştırılmıştır. AA6061 kaynak bağlantıları, takım dönme hızı (2000-2500 dev/dk), kaynak süresi(1-1.5sn), dalma derinliği (1.7-2.0-2.5mm) olmak üzere üç farklı kaynak parametreleri kullanılarak gerçekleştirilmiştir. Yapılan mikroyapısal inceleme sonucunda kaynak bölgesinde karıştırma bölgesi (KB), ısıdan etkilenen bölge (IEB), termo-mekanik etkili bölge (TMEB) ve temel malzeme (TM)olmak üzere 4 farklı bölge tespit edilmiştir. Varyans analizi (ANOVA) sonucunda dalma derinliği parametresinin % 96,76 katkı oranı ile çekme dayanımı üzerinde en etkili parametre olduğu tespit edilmiştir.
