Process Parameters Optimization of Friction Stir Welding for Copper and Aluminium

Mitali Mhatre


Friction Stir welding (FSW) is set of proper sequence of friction based solid state material welding processes. FSW aids in the production of sound welds of non-identical components made of either similar or dissimilar materials, and it has attracted a lot of interest. At present FSW is only using for welding of dissimilar metals. However, due to variance in the physical assets of parent metals, it is problematic to joint these dissimilar metals. The project aim is to weld plates of Copper (Cu) and Aluminium (Al) using FSW to optimize the parameters like tool rotational speed, feed and amount of Zinc in the weld these are affecting the properties of weld joints. The process parameters optimization is conveyed by operating Taguchi method. The main effects analysis is used to complete the optimum grouping of processing parameters at the specific level with highest mean response whereas ANOVA is employed to estimate the error variance and determine the significance of the selected parameters. The forenamed techniques help in form streamlining experimental design, data analysis, and estimate of optimum results. As a result, Taguchi method is considered to be crucial approach to diminish performance variation.
