Mechanical Behavior of Friction Stir Welded Al-Alloy AA6063 + 5%SiCp

Friction stir welding of Al-alloy AA6063-5%SiCp was carried out by applying various permutations of tool rotating velocity and tool traverse velocity using vertical milling machine (VMC). FSW is termed as the green joining technique of the present and future generation. In this research work, the welded joints have been obtained by altering input variables at two-level variation ranges. Tool rotating velocity, tool traverse speed and dwell time were the input variables in this experimental research. Sound weld joints thus obtained were tested for various mechanical properties, namely hardness, tensile strength, etc., during welding process. The results showed that there is a sharp increase in the hardness and tensile strength of the SiC particulate reinforced AA6063. The obtained results were complied with graphs and optical images to analyze the exact behavior.
