STUDY THE EFFECT OF TENSILE STRENGTH IN SINGLE SIDED FRICTION STIR WELDING ON AA6063 ALUMINIUM ALLOY

Friction stir welding is a technique in which the work pieces are joined by profits of frictional heating and plastic deformation indeed a temperature below the melting point of the material to be joint. AA6063 is an aluminium alloy with magnesium and sili con as the alloying element. It has generally good mechanical properties and is heat mendable and weld able. It is similar to aluminium alloy HE9. Experiments are showed by varying rotational speed, transverse speed and altered shoulder diameter. The Taguc hi Method is used to find the combination of the three welding parameters. In this work three parameters are taken and L9 orthogonal array are selected to progress parameters for strength of the welded joint. The Tensile strength is mainly posh by Tool speed and beside it shoulder diameter & feed rate also affect to some extent
