Summary:Friction stir welding is a solid-state welding process with a lot of advantages comparing to the traditional arc welding. In the last years, this process was more and more used in industrial environment to joining by welding a large range of materials, similar and dissimilar. Applicability of this process was identified in automotive industry, aeronautics industry, aerospace industry, railway industry, metal working, research and development, electronic industry, machinery and equipment and others. The friction stir welding process is a simple, this are performed in three steps: a tool is rotated and plunge into the materials until the shoulder meets the surface of upper material, after that the tool keeps rotation, start translation movement and traversed along the direction of welding. At the end of welding seams, the tool has a vertically movement to get out of the plates. This paper presents an experimental study for the welding of three dissimilar aluminium alloys, with different mechanical and chemical properties and the results of it. These three materials are: AA7075, AA2024 and AA6061. The samples obtained with the friction stir welding were tested and analysed considering: process parameters and their influence on tensile properties
