Optimization of Process Parameters in Friction Stir Welding on Aluminum 6061 Alloys

High quality friction stir welding of Aluminum 6061 alloys materials present variety of issues, such welding technique is one of the foremost oftentimes used material joining of two materials AL 6061 Alloy produce a well-defined surface and has surface and tensile strength and high hardness. The tensile strength and hardness and dimensional precision greatly have an effect on the elements throughout their useful life, especially in cases wherever the elements come in contact with different elements or materials. Optimization of machining parameters is an necessary step in machining. This project presents a new approach for optimizing the machining parameters on aluminum 6061 alloy. Optimization of machining parameters was done by Taguchi's L26 orthogonal array and stir welding experiments were conducted for AL 6061 Alloys. The parameters of machining such as, welding speed, rotational speed and tool type are optimized by multi-response concerns particularly tensile strength and hardness. Based on mean effective plots, the optimum levels of parameters have been investigated and significant contribution of parameters is determined by analysis of variance.
