Abstract

In this study, dual phase (DP 600) steel plates with a thickness of 1 mm were joined by copper-based (CuAl8) wire using gas metal arc brazing technique. Specimens were prepared in butt joint form. Brazing operations were done at four different working angles: 50°, 60°, 70°, 80° and 90°, respectively. CuAl8 wire consisted largely of copper served as the filler metal. After completing the brazing operations, the tensile properties as well as the micro- and macro-structures of the joints were analyzed in order to investigate the joinability of DP 600 steel using gas metal arc brazing technique.

Kurzfassung

In dieser Studie wurden 1 mm dicke Bleche aus dem Dualphasenstahl (DP 600) mit dem Kupferbasisdraht (CuAl8) mittels Metall-Inertgaslöten verbunden. Die Proben wurden mit Stumpfnaht vorbereitet. Die Lötungen wurden mit vier unterschiedlichen Arbeitswinkeln, 50°, 60°, 70°, 80° bzw. 90°, durchgeführt. CuAl8-Draht, der weitgehend aus Kupfer besteht, diente als Zusatzwerkstoff. Nach dem Löten wurden die Festigkeitseigenschaften der Verbindungen ermittelt und die Mikro- sowie Makrostrukturen der Verbindungen untersucht, um die Fügbarkeit des DP 600 Stahls durch das Metall-Inertgaslöten zu ermitteln.
