Abstract
Gas tungsten arc welding is a preferred welding process due to its excellent heat control which provides high quality joinings of various metals. Welded armor steels are widely used in armored vehicles for the ease of production. Thus, characterization of gas tungsten arc welding of armor steels reveals important data on both present applications and potential uses of gas tungsten arc welding in future. In this study, microstructural and mechanical properties of welded armor steel were investigated. Optimal welding parameters depending on a previous research were used to eliminate welding defects. The results have shown that application of pre-heating and/or multi-pass welding on armor steel could provide fine and homogeneously dispersed carbides in heat affected zone.
Kurzfassung
Wolfram-Schutzgasschweißen ist aufgrund der hervorragenden Wärmekontrolle ein bevorzugtes Verfahren und ergibt Verbunde mit hoher Qualität bei unterschiedlichen Metallen. Geschweißte Panzerstähle finden wegen der problemlosen Herstellung ein breites Einsatzgebiet bei gepanzerten Fahrzeugen. Daher liefert die Charakterisierung von Wolframschutzgasschweißungen bei Panzerstählen wichtige Daten sowohl für aktuelle Anwendungen als auch für den potentiellen Einsatz des Wolframschutzgasschweißens in der Zukunft. In der vorliegenden Arbeit werden Gefüge- und mechanische Eigenschaften der geschweißten Panzerstähle untersucht. Die bei einer vorherigen Arbeit gefundenen optimalen Schweißparameter wurden zur Elimierung von Defekten berücksichtigt. Die Ergebnisse zeigten, dass durch Vorwärmen und/oder mehrlagiges Schweißen feine und homogen verteilte Karbide in der Wärmeeinflusszone erreicht werden.
