Friction stir welding is a solid state welding which uses non consumable welding tool. It is an automatic process which generally performs on the vertical milling machine. In this type of welding, the relative motion between the tools and work piece creates heat which uses the region of work piece to be welded get softened and to joint the two work pieces. Friction stir welding process is more reliable for the materials which are generally non heat treatable. In this present investigation it will observe that how the rotational speeds of the tool and different shapes of the tool pins effects the mechanical properties of the aluminium alloy 6082. For this purpose three tools with different profiles, i.e triangular, cylindrical and square was designed and fabricated. At three different rotational speeds of 560 rpm, 900 rpm, 1800 rpm work pieces are joined using vertical milling machine. Specimens are prepared and tested for mechanical properties, tensile, impact, and hardness tests are performed and to detect the defects and voids x-ray test performed on the weld joints. And it was observed that highest tensile strength was presented when the square pin tool used at 560 rpm. The rotational speed increased mechanical properties are reducing significantly.

This paper reports on the reconfiguration of a milling machine to produce friction stir welds of aluminium and copper and friction stir processing of 6086 aluminium alloy. Friction stir welding tools were designed and manufactured from tool steel. The tools were inserted into the chuck of the milling machine. A backing plate was also specially designed and manufacturedfrom mild steel to protect the milling machine table and was placed on the bed with the use of T-nuts. The plates were secured firmly on the backing plate with the use of specially designed clamping fixtures. The varied welding speeds and the rotational speeds were achieved using the control system on the vertical milling machine. The reconfigured milling machine was successfully employed to produce friction stir processing of aluminium and friction stir welds of aluminium and copper. An optimum joint strength of 74% was achieved.

Friction Stir Welding was mainly suitable for aluminum alloys due to low softening temperatures. It is challenging to join the high melting temperature metals due to the lack of tool materials. The main focus of this work is to study the feasibility of joining the similar or dissimilar ferrous material. The molybdenum based high speed steel acts a rotating non consumable tool to weld the two ferrous plates. The friction stir welding was achieved using vertical milling machine. Welding samples were examined by destructive and nondestructive test. The welds were produced by 3 mm plate over a range of spindle speed from 500 to 1000 rpm. The results of FSW, stir zone of hardness varies from 139 to 145 HV executed on AISI 1018 plate steel.

Novel Method

In this study, a novel method of mechanical interlocking of super-thin stainless steel strands with different aluminum alloys was conducted by using friction stir forming (FSF). The potential for the development of a multi-functional composite material was studied experimentally. It was concluded that FSF can successfully interlock stainless steel strands and different Al alloys and presents the possibility of improving the mechanical properties of the alloy. Trials of FSF were carried out on a modified vertical milling machine. The results are discussed in terms of microstructure observations, hardness distributions and tensile tests.

Purpose Friction stir welding (FSW) and underwater friction stir welding (UWFSW) of aluminium alloy 2024-T351 was carried out, with a chosen set of parameters, namely, rotational speed of 450 rpm, 560 rpm and 710 rpm, welding speed of 25 mm/min, 40 mm/min and 63 mm/min and tool tilt angle of 0º, 1° and 2º. This study aims to understand the correlation between temperatures and weld parameters, finite element simulation was carried out using Abaqus®. Design/methodology/approach Comparative analysis of the mechanical properties of the samples welded with FSW and UWFSW was carried out and correlated with that of the microstructures. Microhardness survey was also conducted across the weldments to support the findings. Findings Samples welded with higher rotational speed and low traverse speed favoured good quality, defect-free welds with enhanced material flow. Underwater welded samples resulted in improved mechanical properties than that of the samples welded with conventional FSW. Higher cooling rates resulted in finer grains in all UWFSW samples than that of conventional FSW samples, which, in turn, also reflected in the microhardness survey done across the weldments. Among the chosen window of the parameter, samples welded with 710 rpm, 25 mm/min and 2° had shown improvement in mechanical properties. Research limitations/implications This work was carried out in a milling machine, which limits the rotational speed which could be used. Optimistically, this limitation also paves way for using the commonly available milling to be used for FSW. Originality/value This original research study shall open opportunities to enable FSW and UWFSW to be done on similar/dissimilar joints of varying composition. Additionally, this research study throws enough light on the age – hardenable aluminium alloy being welded in a commonly available milling machine.
