Opis:: The article presents the research results on the mechanical properties of aluminum alloy AW-5083 and its joints welded by hybrid method – traditional MIG and FSW. AW-5083 alloy is the most currently used in shipbuilding industry. Friction Stir Welding (FSW) – a new technology can be successfully used for butt-welding of different types of aluminum alloy sheets. FSW method can be an alternative to traditional arc welding methods i.e. MIG or TIG. Hybrid welding (FSW with MIG or TIG) could be used in cases when joining only by FSW is not possible. Welding parameters used for the connection of the sheets were presented. Metallographic analysis showed the correct construction of structural bonded joints. The research was carried out using a static tensile test in accordance with the requirements of the Standard PN-EN ISO 4136:2013-05. Flat samples cut perpendicular to the direction of rolling were used. The research was conducted at the temperature of +20ºC. The test shows that the mechanical properties of joints made by hybrid method compered to native material were lower. The tensile strength of joint was lower by 20% then native material 5083 while its yield stress was lower only about 6%. The biggest change was observed in case of plastic properties. Elongation of joint was over 50% lower compared to native material. Despite the decrease of mechanical properties, they meets the requirements of classification societies, so the conclusion is that hybrid method (FSW and MIG) of joining AW-5083 can be applied in shipbuilding industry.

Opis:: Rapid technological progress in recent years has led to an intensified interest in alternative methods of joining metals. Today’s industry is constantly demanding new joining processes, which enable high-quality welded joints in a wide range of thicknesses of combined materials at low production cost. There are at least several dozen welding methods currently available. The selection of the process depends on the type of welded materials, acceptable heat input, as well as future working conditions. The paper presents the results of the microstructural examination and mechanical properties of joints of the aluminum alloy for plastic working such as EN AW-6082. The paper presents the results of microstructural observations and mechanical properties of EN AW-6082 aluminum alloy. Methods used for joining were successively TIG (welding with a non-consumable electrode in a shield of inert gases), MIG (welding with a consumable electrode in a shield of inert gases), EBW (electron beam welding) along with FSW (friction stir welding method). TIG (welding with a non-consumable electrode in a shield of inert gases), MIG (welding with a consumable electrode in a shield of inert gases), EBW (electron beam welding) along with FSW (friction stir welding method) were used as joining techniques.
Współczesny przemysł wymaga opracowania i udoskonalania metod, które umożliwiają uzyskanie wysokiej jakości połączeń w szerokim zakresie grubości łączonych materiałów oraz obniżenie kosztu produkcji. Istnieje kilkadziesiąt metod spawania. Proces ten trzeba dostosować do rodzaju spajanych materiałów, dostępnych źródeł energii, a także do przyszłych warunków pracy urządzeń. W pracy przedstawiono wyniki badań łączenia najpopularniejszego stopu do przeróbki plastycznej, jakim jest stop EN AW-6082. Metodami wykorzystanymi do łączenia były zarówno najbardziej popularne techniki spawania: TIG (spawanie elektrodą nietopliwą w osłonie gazów obojętnych), MIG (spawanie elektrodą topliwą w osłonie gazów obojętnych), metoda wysokoenergetyczna EBW (spawanie wiązką elektronową), jak również metoda zgrzewania tarciowego z mieszaniem materiały zgrzeiny – FSW.

Opis:: This paper compares, the mechanical properties of welded joints 6061 T6 and 5083 O aluminium alloys obtained using friction stir welding (FSW) at four rotation speeds namely 450,560,710 and 900 rpm and that by conventional fusion welding. FSW welds were carried out on a milling machine. The performance of FSW and Fusion welded joints were identified using tensile test, hardness test and microstructure. The properties of FSW and fusion welded processes were also compared with each other to understand the advantages and disadvantages of these processes for welding applications for Al alloys. It was seen that the tensile strength obtained with FSW was higher as compared to conventional fusion welding process. The width of the heat affected zone of FSW was narrower than Fusion welded joints. The results showed that FSW improved the mechanical properties of welded joints.
