Evaluate the Effects of Friction Stir Welding Parameters on the Impact Strength of Butt Welded Joint

Author : Arti and Deepak Gupta

Friction Stir Welding is basically a combination of extruding and forging process. It can be also stated as a process of Solid State and Thermal – Mechanical Joining. Joining of two metals is widely used in the industrial areas these days which motivates the work in this area. The overall objective of this dissertation work is to evaluate the optimum parameters for the materials under considerations, to obtain the maximum impact strength of the welded joint, the welding process was done by using conventional milling machine. An Izod Charpy test is used to evaluate the impact strength, Suitable parameters were used for the process such as toll rotational speed, tool traveling speed and tool shoulder diameter. It is observed that the impact strength highly influenced by diameter than feed than speed. The experiments were designed by Taguchi methodology. L9 Orthogonal Array was used and Results of the experimentation were analyzed by MINITAB software analytically as well as graphically.
