The joining of dissimilar Aluminium combinations and pure copper is needed in many Engineering industries. For Al/Cu dissimilar welding, the fusion welding techniques are not adequate in light of the fact that after-effects of formation of thick and brittle inter metallic compounds, high residual stresses, blending of material and micro cracks. Keep away from these sorts of imperfections for Al/Cu dissimilar joints utilizing grating mix welding measure Friction stir welding (FSW). This investigation experts to examine the impact of the tool shape and rotational speed on dissimilar joints of 5mm thick AA7075 to pure copper plates. This work is done at four rotational tool speeds of 450 rpm, 560 rpm, 710 rpm, and 900 rpm with a constant feed of 16mm/min utilizing the Tungsten carbide tool (WC). In this examination, the tool pin geometry assumes a significant part in tensile strength and considered two shapes to be specific tapered (cone) tool and cylindrical tool. The performance of the tool shape demonstrated that the pin shape could, in fact, improve the joint strength of the dissimilar welded joint acquired with a tapered pin and furthermore saw that a rotational speed increases formed thick and brittle intermetallic layers and diminishes the rotational speed shaped passage deserts that is tunnel defect at the interface of the weld. Microstructure and SEM pictures of different zones are seen in Al/Cu dissimilar welded joints.
