Abstract

Korozyon, metalin çevresi ile arasındaki
kimyasal reaksiyonların bir sonucu olarak bozulmasıdır. Fakat korozyon, önceden
tahmin edilebilir, bazı durumlarda önemli ölçüde yavaşlatılabilir veya
önlenebilir. Bu çalışmada, pek çok konstrüksiyonun oluşturulmasında kullanılan
imalat yöntemlerinden biri olan kaynak çeşitlerinden soğuk metal transfer
kaynağı ile üretilen AA7075-galvanizli çelik bağlantılarda galvanik korozyon
oluşumunun ve farklı bağlantıların gerilme dayanımına etkisi incelenmiştir.
Alüminyum ve çelik çifti diğer kaynak yöntemleriyle birleştirilmesinin zor
olduğu bir çifttir. Bu yöntem ile birleştirilme sağlanmıştır. Bu çalışmada,
bağlantıda oluşacak korozyon incelenmiştir. Sonuç olarak, kaynak sırasında
artan ısı girişi galvanik korozyonu olumsuz yönde etkiledi ve malzeme
çözünmesini arttırdığı tespit edilmiştir.

Investigation of Corrosion Resistance of Cold Metal Transfer Welded AA7075 Aluminum Alloy Galvanized Steel Couples

Abstract

Corrosion is the degradation of
the metal as a result of chemical reactions with its surroundings. However,
corrosion can be predicted, in some cases significantly slowed down or
prevented. In this study, the effect of galvanic corrosion formation on the tensile
strength of AA7075-galvanized steel joints produced by cold metal transfer
welding, which is one of the manufacturing methods used in forming many
constructions, was investigated. The aluminum and steel pair are difficult to
combine with other welding methods. Joining is provided by this method.
Corrosion in this joining was investigated in this article. As a result,
increased heat input during welding adversely affected galvanic corrosion and
increased material dissolution.
