AbstractFriction Stir Welding (FSW) is one of the modern and constantly evolving technologies of solid state joining and is used for welding a wide range of materials. The main parameters of friction stir welding such as rotational speed of the tool, movement speed and the angle of a tilt are analyzed in this article. 6XXX aluminium alloys have been investigated. The examined mechanical properties of the welds include hardness and strength, which are both important sources of information about quality of welding of the materials used in constructions.

The Status

There is an increase towards reducing the weight of structures through the use of aluminium alloys in different industries like aerospace, automotive, etc. This growing interest would lead towards using dissimilar aluminium alloys which would require welding. TIG and friction stir welding are the well-known techniques that are currently suitable for joining dissimilar aluminium alloys. The welding of dissimilar alloys has its own dynamics which impact on the quality of the weld. This then suggests that there should be a process which can be used to improve the dissimilar alloys welds post their production. Friction stir processing is viewed as one of the techniques that could be used to improve the mechanical properties of the material. This paper reports on the status and the advancement of FSW, TIG and FSP technique. It further looks at the variation use of FSP on TIG and FSW welded joints with the purpose of identifying the knowledge gap.

Triangular Zone

The use of a double sided friction stir welding tool (known as a bobbin tool) has the advantage of giving a processed zone in the workpiece which is more or less rectangular in cross section, as opposed the triangular zone which is more typically found when conventional friction stir welding tool designs are used. In addition, the net axial force on the workpiece is almost zero, which has significant beneficial implications in machine design and cost. However, the response of these tools in generating fine microstructures in the nugget area has not been established. The paper presents detailed metallographic analyses of microstructures produced in 25mm AA6082-T6 aluminium wrought alloy, and examines grain size, texture and mechanical properties as a function of processing parameters and tool design, and offers comparison with data from welds made with conventional tools.

Dissimilar Alloys

The use of aluminium alloys continues to grow in many applications to mention a few aerospace, automotive, electronics, electricity, construction and food packaging. With so much demand there is a new interest in welding of dissimilar aluminium alloys. Some of the welding techniques used to join dissimilar aluminium alloys include friction stir welding and TIG welding. The welding of dissimilar alloys affects the mechanical properties negatively due to porosity and cracking during the welding. This then suggests that there should be a process which can be used to improve the dissimilar alloys mechanical properties post its production. Friction stir processing was found to be one of the mechanical techniques that could be used to improve the mechanical properties of the material. This paper reports on the literature on the friction stir welding, TIG welding and friction stir processing techniques published so far, with the aim to identify the gap in the use of friction stir process as a post processing technique of the weld joints.

There is an increase in reducing the weight of structures through the use of aluminium alloys in different industries like aerospace, automotive, etc. This growing interest will lead towards using dissimilar aluminium alloys which will require welding. Currently, tungsten inert gas welding and friction stir welding are the well-known techniques suitable for joining dissimilar aluminium alloys. The welding of dissimilar alloys has its own dynamics which impact on the quality of the weld. This then suggests that there should be a process which can be used to improve the welds of dissimilar alloys post their production. Friction stir processing is viewed as one of the techniques that could be used to improve the mechanical properties of a material. This paper reports on the status and the advancement of friction stir welding, tungsten inert gas welding and the friction stir processing technique. It further looks at the variation use of friction stir processing on tungsten inert gas and friction stir welded joints with the purpose of identifying the knowledge gap.

Aluminium alloys reveals good mechanical properties when soldered with Friction Stir welding. Thus to get these preferred mechanical properties, particular welding procedure parameters are to become examined. Nowadays aluminium alloys have actually been actually extensively used in industrial uses like aerospace and automobile as a result of their light weight, really good mechanical properties as well as high corrosion resistance. In this work, 3 process parameters including spindle rate, assembly rate and also jump intensity were actually looked at for abrasion rouse assembly. The paper pays attention to technique guidelines that sought after producing effective friction stir welding function.

ABSTRACTFriction Stir Welding (FSW) is a novel solid-state joining process where the work pieces are joined together using a rotating non-consumable tool. The process has mainly been used for joining aluminium alloys, and has not yet been used in production for any other metal. However, the results from the development program confirm that FSW can consistently seal 50mm thick copper canisters without creating defects. A new machine is now installed at SKB's Canister Laboratory to further automate the process to production level.

The Stationary Shoulder Friction Stir Welding (SS-FSW) technique benefits from reduced heat input, improved mechanical properties and surface finish of the weld, avoiding the need for post weld processing. Coatings on the tool probe and the shoulder for welding of aggressive Aluminium alloys have rarely been successful. Such coatings must be well adherent and inert. In this study, coated tools were used for SS-FSW of AA6082-T6 alloy. Performance of a nanoscale multilayer TiAlN/VN coating deposited by High Power Impulse Magnetron Sputtering (HIPIMS) technology was compared with amorphous Diamond Like Carbon (a-C:H) by Plasma Assisted Chemical Vapour Deposition (PACVD), AlTiN deposited by arc evaporation and TiBCN along with TiB2 produced by Chemical Vapour Deposition (CVD) methods. The TiAlN/VN coating was found to have low affinity to aluminium, acceptable coefficient of friction and provided excellent weld quality by inhibiting intermixing between the tool and workpiece materials resulting in a significant reduction in tool wear.
