Experimental Investigation and Analysis of Tensile Strength of Dissimilar Friction Welded Joints of Aluminium 6061 and Mild Steel
Nowadays, the joining process plays a vital role in every field of engineering application. Various similar and dissimilar materials are joined by many joining processes to a formed complex component. In all joining processes, welding is a very popular and effective joining process that gives permanent joint. In this process material to be joined is under influence of heat which is produced with aid of external (flame) and internal (friction) mediums. Further, there are types of welding process called friction welding which is solid-state welding, in that process friction had developed between materials having relative motion thus sufficient heat also produced, and welding is performed in solid-state. In recent time’s friction welding is widely used in automobile, aeronautical, structural, marine, etc areas due to its flexibility demand for various materials. In this research work, the aluminium 6061 and mild steel are joined by friction welding by varying the rotating speed of lathe chuck, friction time, burn-off length, and the joint is examined by a tensile test to check its strength. Taguchi’s orthogonal array was used to design the experiment and at the end, the ANOVA test is carried out for the optimization of process parameters.
