Abstract

In the present study, the effect of two different pins which shaped in the triangular and straight helical threaded were associated with the ratio of the tool rotational speed to the welding speed on the mechanical properties of dissimilar friction stir welding (FSW) of EN AW 6082 and EN AW 5754. The responses of FSW process were investigated by the UTS, Ɛ% and hardness of weld joint. The results showed that the ratio of the tool rotational speed to the welding speed have a dominant effect on the weld joint strength. 

Takım Dönme Hızının Kaynak Hızına Oranı ve Pim Şeklinin Mekanik Özellikler Üzerine Etkisi

Abstract

Bu çalışmada EN AW 6082 ve EN AW 5754 malzemelerin birbiri ile FSW kaynağında helisel diş açılmış
ve üçgen şekilli iki farklı pim ile takım dönme hızının kaynak hızına oranının mekanik özellikler üzerine etkisi
incelenmiştir. FSW işleminin sonuçları kaynaklı bağlantının maksimum çekme mukavemeti, % şekil değiştirme
ve sertliği ele alınarak incelenmiştir. Sonuçlar takım dönme hızının kaynak hızına oranının kaynaklı bağlantının
mukavemeti üzerine çok önemli bir etkiye sahip olduğunu göstermiştir.
