The joining of dissimilar Aluminum Alloy and Copper aluminum plates of 5mm thickness was carried out by friction stir welding (FSW) technique. Optimum process parameters were obtained for joints using statistical approach. Five different tool designs have been employed to analyse the influence of rotation speed and traverse speed over the microstructural and tensile properties. In FSW technique, the process of welding of the base material, well below it’s melting temperature, has opened up new trends in producing efficient dissimilar joints. Effect of welding speed on microstructures, hardness distribution and tensile properties of the welded joints were investigated. By varying the process parameters, defect free and high efficiency welded joints were produced. The ratio between tool shoulder diameter and pin diameter is the most dominant factor. From microstructural analysis it is evident that the material placed on the advancing side dominates the nugget region. The hardness in the HAZ of 6061 was found to be minimum, where the welded joints failed during the tensile studies. INTRODUCTION 1.1 WELDING Two metals that are similar or dissimilar can be welded together by the process of welding by being heated to the proper temperature either under stress or not, and with no addition of filler metal. the metal filler's temperature is typically around 430 degrees centigrade, and it is either roughly the same as or a bit lower than rock's melting point. Several methods are used to heat the edges of the work piece during welding. Heat can be produced by an electric arc, an oxy-acetylene or oxy-hydrogen flame, a blacksmith's fire, or a chemical reaction, such as occurs during thermit welding.
