Description :
In this study, application of friction stir welding (FSW) process to join stir casted aluminium–copper matrix-based composites reinforced with SiCp is investigated. FSW is a novel solid state joining technology in which a non-consumable rotating tool is used to produce frictional heat between the rotating tool and fixed work piece in order to make weld joint. The welding parameters such as welding speed, tool rotational speed, and profile of the tool were considered for analysis. An attempt is made to investigate the effect of process parameters of FSW on the ultimate tensile strength (UTS) of the welded joints. Rotational speed, welding speed and tool pin profile in the order considered are found to be the major influencing parameters on the joint strength. Optimization of process parameters is carried out using Taguchi L18 orthogonal array design. Based on the analysis of variance, optimum process parameters are identified and validated by confirmation tests.
