Abstract

Friction stir welding (FSW) is a solid phase welding method, developed for aluminum alloys by The Welding Institute (TWI), which is applied in non-traditional welding techniques. The industrial applications of this method have been intensified in recent years. In this method, parts in various geometries can be joined in solid state. In this study, Al-Mg based 5083 aluminum alloys, which are widely used in industry, were joined by friction stir welding method and the mechanical properties of the joints were determined. The mechanical properties of joined parts were experimentally investigated using tensile, hardness and fatigue tests for 550, 700, 800 and 1400 rpm rotation speeds with 40 mm × min⁻¹ and 80 mm × min⁻¹ progressing speed, respectively.

Kurzfassung

Das Rührreibschweißen (Friction Stir Welding (FSW)) ist ein Schweißprozess im festen Zustand und wurde vom „The Welding Institute“ (TWI) für Aluminiumlegierungen entwickelt. Es wird bei nicht-traditionellen Schweißtechniken verwendet, wobei sich die industriellen Anwendungen des Verfahrens in den letzten Jahren intensivieren. Mit diesem Verfahren können Teile mit verschiedenen Geometrien verbunden werden. In der diesem Beitrag zugrunde liegenden Studie wurden Al-Mg-basierte Aluminiumlegierungen, die in der Industrie breitflächig eingesetzt werden, mit dem Rührreibschweißprozess verbunden und die mechanischen Eigenschaften der Verbindungen ermittelt. Mittels Zugversuchen, Härtemessungen und Ermüdungstests für Umdrehungsgeschwindigkeiten von 550, 700, 800 und 1400 U × min⁻¹ und Vorschubraten von 40 mm × min⁻¹ und 80 mm × min⁻¹ wurden diese experimentell bestimmt.
