Özet

Bu çalışmada otomotiv endüstrisinde yaygın olarak kullanılan, ileri mukavemet özelliklerine ve farklı kalınlıklara sahip 22MnB5, DP980 ve TBF1180 malzemelerin lazer kaynak yöntemi ile kaynaklanabilirlikleri araştırılmıştır. Kaynak işlemlerinde endüstride yoğunlukla kullanılan fiber lazer kaynak yöntemi tercih edilmiş ve kaynak işlemleri robotik olarak yapılmıştır. Birleştirilen malzemelerin mekanik özelliklerini belirlemek için çekme testi, şekillendirilebilirlik özelliklerini belirlemek için ise Erichsen çökertme testleri yapılmıştır. Ayrıca numunelerin kaynak bölgeleri sertlik testi ve mikroyapı incelemeleriyle karakterize edilmiştir. Mikroyapı incelemelerinde tüm birleştirmelerde kaynak metalinin ağırlıklı olarak martenzitik yapıda olduğu görülmüştür. Sertlik test çalışmalarında tüm numunelerde ısı tesiri altında kalan bölgede (ITAB) yumuşak bir bölgenin olduğu tespit edilmiştir. Çekme testleri sonucunda kaynaklı bağlantı verimleri %70-95 olarak hesaplanmıştır. Erichsen çökertme testinde, yırtılmaların kaynak metaline paralel ancak kaynak metalinin dışından (ergime sınırı, ITAB) gerçekleştiği görülmüştür.
