Abstract
In this work, the friction stir welding of aluminium alloy was done on the hybrid storage tank-assisted fixture at the vertical milling centre (VMC). The three different storage media were used as air, water and coolant. This study aimed to examine the effect of the cooling media in the hybrid fixture on the wear, coefficient of friction (COF), hardness and worn surface of welded samples. The tool of mild steel was used for the welding process, and the wear of the tool was also examined for a better recommendation of tool material. The FSW of the coolant-type welding process found that the least wear was obtained at the different welding conditions. In the FSW of the coolant-type welding process, it was found that the least wear was obtained at the different welding conditions. The higher rotational speed welded FSW joint increases the wear. The COF exceeds the base material at 900 rpm in the FSW-W type joint. The average value of friction force (FF) at 500 rpm and 1000 m sliding distance was 3 N FSW air (FSW-A) and 5 N base material. The average value of FF at 700 rpm and 1000 m sliding distance was 1 N FSW-A and 6 N for base material. The FF at 900 rpm was 5 N FSW water type (FSW-W) and 1 N for FSW -A.
