Abstract
Laser welding is a high energy density-low heat input technique which has many advantages according to the classical welding techniques. Nowadays laser welding technique is being used widely in
many industrial applications. In recent years, for welding of thin metals laser technology is growing
up. This research includes, butt welding of 0,6 mm thick ferrite 430 quality stainless steel. Stainless
steel thin work pieces have been welded by use of fiber laser welding machine with different parameters (pulse diameter, pulse energy, pulse time, pulse frequency) to achieve better mechanical properties
than original material at the weld area. Micro structure, stress tests have been applied to determine and
compare the mechanical properties. Optical microscope has been used to examine the micro structure.
The corrosion properties of the welds were examined and it was seen that intergranular corrosion and
pitting occurred in the weld zone.

Abstract
Lazer kaynağı, geleneksel kaynak yöntemlerine göre birçok avantajı olan yüksek enerji yoğunluklu,
düşük ısı girdili bir kaynak yöntemidir. Bugün sanayinin birçok alanında endüstriyel olarak sıklıkla
kullanılmaktadır. Son yıllarda ince malzemelerin kaynağında da lazer teknolojisinin kullanımı artmıştır. Bu çalışmada, 0,6 mm kalınlığında ferritik 430 kalite paslanmaz çelik malzemelerin alın kaynak
kabiliyeti incelenmiştir. Paslanmaz çelik levhalar darbeli fiber lazer kaynak makinası ile çeşitli kaynak parametreleri (ışın çapı, darbe enerjisi, darbe süresi, darbe frekansı) değiştirilerek kaynak edilmiştir. Kaynaklı bağlantıların mekanik özelliklerini belirlemek için çekme testleri uygulanmıştır. Ayrıca metalurjik özelliklerini değerlendirmek için optik mikroskop görüntüleri incelenmiştir. Kaynak
bölgesinin korozyon özellikleri incelenmiş ve taneler arası korozyon ve pitting oluşumunun meydana
geldiği görülmüştür.
