Abstract
In the present work, microstructural and mechanical characterization of electric resistance welded (ERW) low carbon steel specimens has been carried out. The tensile strength of the samples is 448 MPa and the ductility is 29.70 %. The microstructure revealed the presence of fine grains of pearlite and ferrite with large proportion of ferrite and small proportion of pearlite. It also revealed the presence of inclusion in the parent metal which is due to improper calcium treatment. Lack of fusion is also seen in one sample, which may be due to higher heat input. Energy dispersive spectroscopy revealed the presence of oxides in inclusion as well as lack of fusion region.
Kurzfassung
In der vorliegenden Arbeit wurde eine mikrostrukturelle und mechanische Charakterisierung von Proben aus kohlenstoffarmem Stahl durchgeführt, die mittels elektrischen Widerstandschweißens geschweißt wurden. Die Zugfestigkeit der Proben beträgt 448 MPa und die Bruchdehnung 29,70 %. Die Mikrostruktur zeigte das Vorhandensein feiner Perlit- und Ferritkörner mit einem hohen Ferrit- und einem geringen Perlitanteil. Außerdem wurden Einschlüsse im Grundmetall festgestellt, die auf eine unsachgemäße Behandlung mit Kalzium zurückzuführen waren. Bei einer Probe wurde auch eine mangelnde Verschmelzung festgestellt, die möglicherweise auf eine zu hohe Wärmezufuhr zurückzuführen ist. Die energiedispersive Röntgenspektroskopie zeigte das Vorhandensein von Oxiden in den Einschlüssen und in der fehlgeschmolzenen Region.
