Nokta Direnç Kaynağı ile Birleştirilen Geliştirilmiş Yüksek Mukavemetli Çeliğin Mekanik Özellikleri Üzerinde Elektrod Uç Tipinin Etkisinin İncelenmesi

Öz

Bu çalışmada, nokta direnç kaynak yöntemi ile birleştirilen geliştirilmiş yüksek mukavemetli çeliğin kaynak çekirdek çapı, çekme makaslama dayanımı ve mikrosertlik özellikleri üzerinde farklı elektrot uç tiplerinin etkisi incelenmiştir. Bu amaçla, özellikle otomotiv sektöründe tercih edilen konik yuvarlak, düz R3, düz R6 ve düz konik elektrot uçlar kullanılarak nokta direnç kaynaklı birleşimler gerçekleştirilmiştir. Deney numuneleri, kaynak çekirdeği geometrisi makro-mikro incelemesi, mekanik ve metalürjik incelemelere tabi tutulmuştur. Deneysel sonuçlar kaynak çekirdek çap değeri, mikro sertlik sonuçları ve çekme makaslama dayanım değerleri arasında doğrusal bir ilişki olduğunu göstermiştir. Düz 3 mm yarıçap uçlu elektrotlar ile en yüksek, düz konik uçlu elektrotlar ile en düşük çekme makaslama dayanım değerleri elde edilmiştir.

Anahtar Kelimeler

Nokta direnç kaynağı , elektrot uç tipi , kaynak çekirdek çapı , çekme makaslama dayanımı , mikrosertlik
