Abstract

The aim of this study is to investigate the effect of a monel/nickel interlayer electrode prepared with a thickness of 2 mm on the weldability properties of duplex stainless steel plates welded by means of plasma transfer arc welding. After welding, scanning electron microscopy, X-ray diffraction and energy dispersive spectrometry were carried out to determine the microstructural changes that occurred in the interface regions of the welds. Moreover, tensile strength, microhardness and fractography tests were conducted for assessing the mechanical properties of the welded specimens. The results of tests and examinations indicated that the tensile strength of welded parts with a nickel interlayer was higher than that of with and without a monel interlayer.

Kurzfassung

Ziel der diesem Beitrag zugrunde liegenden Studie ist es, die Auswirkungen einer Monel/Nickel-Zwischenlagenelektrode mit einer Dicke von 2 mm auf das Verhalten beim Lichtbogenplasmaschweißen und die Eigenschaften von Schweißverbindungen an Duplexstahlblechen zu untersuchen. Nach dem Schweißen wurden hierzu REM-, Röntgendiffraktometrie- und EDS-Untersuchungen durchgeführt, um die mikrostrukturellen Änderungen, die an den Übergangsflächen der Schweißnahtverbindungen auftreten, zu analysieren. Darüber hinaus wurden die Zugfestigkeit und die Mikrohärte bestimmt, sowie fraktografische Prüfungen vorgenommen, um die mechanischen Eigenschaften der Schweißverbindungen zu bestimmen. Die Ergebnisse der Prüfungen und Untersuchungen deuten darauf hin, dass die Zugfestigkeit der mit einer Nickel-Zwischenlage geschweißten Proben höher als die der mit bzw. ohne Monel-Zwischenlage geschweißten Proben ist.
