Sažetak
Cilj rada je osvajanje tehnologije zavarivanja aluminijumskih legura postupkom zavarivanja trenjem alatom (FSW). Zavarivanje trenjem alatom predstavlja jedan od najsavremenijih postupaka, sa velikom perspektivom dalje primene, pošto pruža najraznovrsnije mogućnosti za zavarivanje raznorodnih materijala. U radu su analizirani eksperimentalni rezultati su čeono zavarenih spojeva aluminijumskih ploča zavarenih postupkom zavarivanja trenjem alatom. Izvršeno je poređenje raspodele tvrdoće u zavarenom spoju u zavisnosti od parametara zavarivanja odnosno količine unete toplote u zoni zavarivanja, debljine ploča i tipa aluminijumske legure.
Abstract
The objective of this paper is a development of welding technology of aluminium alloys by Friction Stir Welding (FSW). FSW is a very modern welding process with a great future use, primarily due to a variety of possible combinations of dissimilar materials to be welded. In this paper experimental results of butt welds for the friction stir welding of aluminium alloys are analyzed. A comparison hardness distribution in the welds was done considering welding parameters, that is the quantity of heat in the welding zone, panels thickness and aluminum alloy type.
