Optimization of Friction Stir Welding Parameters for the Optimum Hardness of Al–Cu Butt Joints Using the Taguchi Method
摘要
In the present study, the base plates made of alloys AA6101 and C11000 (each 5 mm thick) were welded by the FSW technique using a hardened OHNS steel weld tool. The percentage contribution of the input process parameters, such as tool rotational speed in rpm, feed rate in mm/min, and tool pin offset in mm, on the output parameter joint hardness, were examined using the experimental design Taguchi L9 and ANOVA numerical tool analysis. From the optimization method, at 1000 rpm tool rotational speed, 40 mm/min feed rate and weld tool pin toward AA6101 alloy side will have the highest hardness. The tool rotational speed experiences a maximum significant impact on the joint hardness.
