Abstract

In this study, AA 4000 series Al-Si alloys sheets were joined by TIG welding method using alternative and pulsed current. Tensile test, hardness test and microstructure examination of joined test specimens were carried out in order to see the effect of current type on mechanical properties of welded samples. Experimental results showed that, pulsed current leads to low heat input, grain refinement and hardness increase in weld metal compared to alternative current were used. Specimens joined by the pulsed current showed higher tensile strength than the specimens welded by the alternative current.

Özet

Bu çalışmada, AA 4000 serisi Al-Si alaşımı levhalar gazaltı kaynak yöntemlerinden olan TIG kaynak yöntemi ile alternatif ve darbeli akım kullanılarak birleştirilmişlerdir. Kullanılan akım türünün kaynaklı levhaların özelliklerine olan etkilerini görmek amacı ile birleştirilen numunelere mikroyapı, sertlik ve çekme testleri uygulanmıştır. Deneyler sonucunda, darbeli akımın ısı girdisini düşürdüğü, kaynak metali tanelerini incelttiği ve geleneksel alternatif akıma göre kaynak metali sertliğinde artışa neden olduğu belirlenmiştir. Birleştirilmiş levhalara uygulanan çekme testlerinde, darbeli akım ile birleştirilen numunelerin alternatif akıma nazaran daha yüksek çekme dayanımı gösterdikleri tespit edilmiştir.
