Joining of dissimilar materials is one of the most essential needs of industries. There are various welding methods that have been developed to obtain suitable joints in various applications. However, friction welding is a solid-state joining technique which utilizes the heat generated by rubbing of two faying surfaces for the coalescence of material. In the present study, an experimental set-up was designed in order to achieve friction welding of plastically deformed Al 7075 and Al 6061. Samples were welded under different burn-off lengths and different rotational speeds. The tensile strengthof the welded joints was determined and evaluated and on the basis of the results obtained from the experimentation, the graphs were plotted. The experimental results indicate that burn-off length and rotational speed has a significant effect on the tensile strength of the joint and it is possible to increase the quality of the welded joint by selecting the optimum burn-off lengths and rotational speeds.
