Bu çalışmada, dört farklı kalınlıktaki AA6061-T6 levhaların sürtünme karıştırma kaynağı ile hatasız birleştirilebilmesi için kullanılması gereken kaynak parametreleri belirlenmeye çalışılmıştır. Bu amaçla, her bir levha kalınlığı için bir olmak üzere, dört farklı karıştırıcı takım temin edilmiş ve bu uçlar kullanılarak her bir levha kalınlığı için uygun kaynak parametreleri tayin edilmiştir. Elde edilen kaynaklı bağlantıların makro ve mikro boyutta içyapısı incelenmiş, çekme deneyi ve sertlik ölçümleri ile mekanik özellikleri belirlenmiştir. Bu çalışma, farklı kalınlıklardaki AA6061-T6 alaşımı levhaların uygun karıştırıcı takımlar ve kaynak parametreleri ile başarılı bir şekilde birleştirilebileceğini ortaya koymuştur.
