Bu çalışmada otomotiv endüstrisinde kullanılan 5000 serisi alüminyum
alaşımlarından olan Al 5754-H111 malzemesi elektrik direnç kaynak yöntemi ile
farklı kaynak akımı, kaynak süresi ve sıkıştırma yükü ile birleştirilmişlerdir.
Kaynak işlemi uygulanmış numunelerin mekanik özelliklerini belirlemek amacıyla kaynaklı
bağlantılara çekme deneyi yapılmıştır. Test sonuçlarına göre elde edilen çekme
mukavemeti ve çekme uzaması değerlerindeki farklılıklar, kaynak
parametrelerindeki değişimin kaynağın mekanik özellikleri üzerinde önemli
etkiye sahip olduğunu göstermiştir.

In this study, Al 5754-H111 material from 5000 series
aluminum alloys used in the automotive industry were combined with different
welding current, welding time and compression load by electrical resistance
welding method. Tensile tests were performed to determine the mechanical
properties of welded specimens. The differences in tensile strength and tensile
elongation values obtained from the test results have shown that the variation
in weld parameters has a significant effect on the mechanical properties of the
weld.
