Nowadays, aluminium and aluminium alloys are most widely used in many applications in which the combination of high strength and low weight is attractive. Friction Stir Welding (FSW) process is an efficient and cost-effective method for welding aluminium and aluminium alloys. FSW is a solid-state welding process in which the material is not melted during the process. Being a solid state process it overcomes many welding defects that usually happens with conventional fusion welding techniques which were initially used for low melting materials. Though this process is initially developed for low melting materials but now the process is widely used for a variety of other materials. In this present experimental investigation, initially, butt joining of similar aluminium alloy AA6351 with AA6351 and dissimilar aluminium alloy AA6351 with AA5083 of 5 mm thickness were carried out by FSW and compared tensile properties. To study the influence of another element such as copper and brass on both combinations have been carried out. FSW has been done by inserting 0.1 mm thickness of copper and brass foil separately in butt joint position for both similar and dissimilar aluminium alloy combinations by changing the rotational speed of the tool. Tensile properties studied for all these combinations and results were compared using with and without foil of copper and brass material.Keywords

Friction Stir Welding (FSW) technique is newly developed solid state type of welding process. This process is gaining more importance and applied in various industries due to quality of joint is good compared to other welding techniques. This process utilises a rotating tool consists of shoulder and probe. The tool is non-consumable and harder than material to be welded. The tool generates heat due to friction between the probe and abutting surface of the workpiece to complete the welding process. Being a solid-state nature, FSW offers numerous advantages and produces a high strength joint when compared to fusion welding processes. In this work, an experimental work is carried out between two aluminium alloy plates to study the influence of rotation speed of the tool on prepared FSW weldments. Aluminium AA6351 alloy plates of 5 mm thickness is joined in butt joint. These two plates were joined by FSW process by changing tool’s rotation speed. The tensile test has been performed for all these weld samples. A numerical investigation is carried out to validate the tensile strength test results.

The features like low weight, low cost with moderate strength of aluminium (Al) alloys fascinate various modern industries to replace steels in different applications. The newly invented FSW (Friction Stir Welding) is well suited for Al alloys compared to other conventional welding processes. The solid-state type of this process overcomes melt-related defects when compared to fusion welding processes. It also overcomes many other defects like voids, cracks, and distortion and forms sound weld joint. FSW joints show a fine clear grain structure in the weld nugget area compared to the parent material. In this investigation, tensile properties and microhardness properties of Al AA6010-T6 alloy are studied.Keywords
