On various mechanical properties of Aluminium alloy 6063 produced by friction stir welding have been analyzed. Friction stir welding is a technique in which the work pieces are merged by profits of frictional heating and plastic deformation certainly a temperature below the melting point of the material to be joint. AA6063 is an aluminium alloy with magnesium and silicon as the alloying element. It has generally moral mechanical properties and is heat mendable and weld able. It is similar like to aluminium alloy HE9. Experiments are exposed by varying rotational speed, transverse speed and altered shoulder diameter. The Taguchi Method is used to treasure the combination of the three welding parameters. In this work three parameters are taken and L9 orthogonal array are selected to development parameters for strength of the welded joint. An optimal result has been obtained using main effects plot using S/N ratio values. The elongation is mainly posh by temperature distribution and near it shoulder diameter & feed rate also affect to some extent.

INTRODUCTION Aluminium alloys in the present modern world are suitable for wide applications including automobile industries, aerospace, railway fabrication, high speed ships and construction of heavy structures due to its light in weight and higher strength to weight ratio properties. Friction stir welding (FSW) developed by The Welding Institute (TWI), in 1991 is one of the sensibly current solid state welding technique. [1] The ASM description for a welding process is “a materials joining process which creates amalgamation of materials by heating them to decent suitable temperatures with or without the application of pressure or by the application of pressure alone and with or without the usage of filler material.”[2].
