Hemant Sahu, Manjit Lakra, S P Shrivas
ABSTRACT
Friction stir welding can be controlled by different parameters these parameters are optimized for welding of two different grade material that is aluminum alloy 6082 and aluminum alloy 5083. Friction stir welding (FSW) was selected for the joining of lap and butt welded parts having 100 x 50 x 5mm thick sheets each. They were tested for mechanical properties such as tensile strength and Charpy Test respectively. In this experiment using the selected control parameters are Rotational speed, Welding speed, and Tool Tilt Angle. The three control parameters each are three 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 predicted by Grey Relation analysis.
