Investigation of mechanical properties of high strength steel welded by resistance spot welding

Abstract: Bu çalışmada farklı kalınlıklardaki DP 800, Usibor 1500 ve Ductibor 500P olmak üzere üç farklı yüksek mukavemetli çelik sac malzeme elektrik direnç nokta kaynağı ile birleştirilmiştir. Kaynak işlemi elektrik akımı, basıncı ve süresi gibi sabit parametreler altında farklı malzeme kombinasyonlarında yapılmıştır. Aynı ve farklı malzeme çiftleri için bindirme şeklinde elektrik direnç nokta kaynağı uygulanarak standartlara uygun çekme numuneleri hazırlanmıştır. Bağlantıların mekanik özellikleri sertlik ve çekme-mak… Show more

“…It is also stated fracture was caused by the high hardness of the weld and the fragile microstructure, as well as the concentration of stress from the boundary of the nugget. Aras et all [19] had been investigated mechanical properties of RSW welded DP800, as-received Usibor1500 and Ductibor 500P three advised high strength steel with different thickness. According to the result they reached, when different types of steels are welded together, the maximum tensile-shear force and elongation achieved are higher than those of same type of materials.…”
