ABSTRACT

Friction Stir Welding is a solid-state process, which means that the objects are joined before reaching the melting point and is a newly developed welding technique utilized to weld lightweight alloys, such as aluminum alloys. Low heat generation in friction welding causes poor joint due to a minimum speed of rotation, welding strength on aluminum alloy has been always challenging using conventional techniques. Welding strength can be obtaining maximum to control friction stir welding parameters like rotational speed, welding speed, and welding medium. In this research, friction stir welding of aluminum alloy 8011 & welding this with its similar plate having a cross section of 100 x 50 x 10 mm thick. The present work shows that similar materials have the highest effect on the mechanical properties of the specimens taken from the welded zone. They were tested for mechanical properties such as tensile strength and Charpy Test respectively. In this experiment using the selected control parameters are Temperature, holding time and cooling medium. The three control parameters each are two levels has been designing the experiment based on full factorial method. These results show that Charpy impact test and tensile stress increased with increase the parameter level. The optimum process parameters for the maximum tensile strength and Charpy impact joints were compared and discussed the effects.
