Abstract

The increasing application of innovative materials, such as high strength aluminum alloys, is challenging the manufacturing processes of the Aerospace and Aeronautics Industries. Despite this challenge the processes need to comply with high requirements regarding the reproducibility and the quality of the products. For this reason the adaption of conventional welding technologies to the new materials is considered to be difficult. Therefore, innovative welding technologies such as Friction Stir Welding (FSW) have been developed Friction Stir Welding is a well solid state joining technology. Many processing conditions and materials properties affect the microstructural evolution and mechanical behavior of the made joints. The main parameters involved in the welding process have been studied and the results presented in the present study. The analysis was conducted through employing a multi-objective optimization tool capable of correlating all the material properties and processing parameters to the final mechanical performances of the welds. The Aluminium alloy plates of are welded in rectangular butt joint geometry by friction stir welding (FSW) process, using CNC vertical milling machine. Process parameters such as welding speed and tool rotational speed play an important role to obtain a better weld joint for similar metals/materials. The friction stir welding tool is one of the critical components to the success of this process. It consists of a cylindrical shoulder and a pin with different geometry. In the experimental work, tool has been made with cylindrical pin having four different geometries for friction stir welding of the similar circular metal plates. Effects of process parameters on butt welded rectangular joint were investigated for weld strength.
