Abstract
The welding of metal matrix material reinforced with ceramic particles has some problems such as formation of oxide layer, segregation occurring on welding area, and reaction of ceramic particles with welding bath. The expected mechanical properties cannot be obtained because of these problems. In this study, the weldability of aluminum 2014 alloy reinforced with SiC particles was investigated. MIG welding process was used via using AlSi5 alloy wire at different types and values of welding currents. Samples obtained using manual welding current were compared to those obtained using pulse welding current, in terms of microstructure and distribution of hardness. The effects of different types and values of welding currents on the microstructure and hardness distribution were examined. It was obtained that the welding of the composite with aluminum 2014 alloy matrix reinforced with SiC particles via using of pulse current, potential formation of segregation was prevented and microstructural properties were improved.

Abstract
Metal matrisli ve seramik partikül takviyeli malzemelerin kaynağında oksit tabakası oluşumu, kaynak bölgesinde segregasyon meydana gelmesi ve seramik partiküllerin kaynak banyosu ile tepkimeye girmesi gibi nedenlerden dolayı sorunlar ortaya çıkmaktadır. Bu sorunlar nedeniyle beklenen mekanik özellikler elde edilememektedir. Bu çalışmada, SiC takviyeli alüminyum 2014 alaşımının kaynak edilebilirliği araştırılmıştır. AlSi5 alaşımı tel kullanılarak, MIG yöntemiyle yapılan kaynak işlemlerinde farklı türde ve farklı değerlerde kaynak akımları kullanılmıştır. Manuel kaynak akımı ile elde edilen numuneler ile pulse kaynak akımı ile elde edilen numuneler mikroyapı ve sertlik dağılımı açısından karşılaştırılmıştır. Farklı kaynak akım türünün ve değerlerinin kaynak mikroyapı ve sertlik dağılımı üzerindeki etkisi incelenmiştir. Alüminyum 2014 matrisli ve SiC partikül takviyeli kompozitin kaynağında pulse akım kullanılması sonucunda, kaynak bölgesinde meydana gelebilecek segregasyon önlenmiş, mikroyapı özelliklerinin iyileştiği tespit edilmiştir.
