In fact , joining of aluminium alloys could be frequently faced in many cases including automotive, aerospace, electronics and shipbuilding industries, Where fusion welding simply is not appropriate due to the large difference of physical and chemical properties between the components to be joined. Problems including porosity formation, solidification cracking, and chemical reaction may arise during fusion welding of dissimilar materials although sound welds may be obtained in some limited cases with special attentions to the joint design and preparation, process parameters and filler metals. In contrast, friction stir welding (FSW) seems to be a very promising technique as it permits welding of aluminium alloys while avoiding the drawbacks of fusion welding. Products made of aluminium alloys have been becoming increasingly significant in industrial applications because of their technical and economic benefits. Many people carried out the welding tests on the aluminium alloys with taking the various parameters take in to consideration for the process. We are taking the material mentioned above for FSW tests with some different parameters. Also we will do the experimental study of the same welding joint. Finally, the direction of future research and potential applications are examined and it will become good option to the other welding processes.
