Abstract

In this study, AISI 4140 steel couples 10 mm in thickness were joined using manual gas metal arc (GMAW) and synergic controlled pulsed gas metal arc (GMAW-P) welding methods. Interfacial images of welded samples were investigated using optical microscopy (OM), scanning electron microscopy (SEM), energy dispersive spectrometry (EDS) and X-ray diffraction (XRD) methods. Impact and microhardness tests were performed to determine the mechanical properties of the joined parts. In addition, the fracture surface of the broken joint with the impact test was examined using SEM. The AISI 4140 welded joints obtained by the GMAW-P method showed higher impact strength, less grain growth and narrower heat affected zone (HAZ) than by using the GMAW method. It is thought that this is caused by lower heat input.

Kurzfassung

In der diesem Beitrag zugrunde liegenden Studie, wurden 10 mm dicke Bleche des Stahles AISI 4140 mittels des manuellen MAG-Schweißprozesses ungepulst und kontrolliert gepulst verbunden. Die Verbindungszone wurde mittels Lichtmikroskopie, Rasterelektronenmikroskopie sowie mittels EDS- und XRD-Analysen untersucht. Außerdem wurden Kerbschlagversuche und Mikrohärtemessungen durchgeführt, um die mechanischen Eigenschaften der Verbindungen zu prüfen. Zusätzlich wurden die Bruchoberflächen der Kerbschlagproben mittels REM untersucht. Die Verbindungen des Stahles AISI 4140, die mittels des gepulsten MAG-Prozesses hergestellt wurden, wiesen eine höhere Festigkeit, ein geringeres Kornwachstum und eine schmalere Wärmeeinflusszone als die mittels des ungepulsten MAG-Verfahrens hergestellten Proben auf. Es wird angenommen, dass dies auf die geringere Wärmeeinbringung zurückzuführen ist.
