Joining of aluminium to polymer by friction stir welding: An overview

Friction stir welding (FSW) is a potential fabrication method to join the aluminium and polymer dissimilar materials as FSW joins the metals below their melting point. Since the automobile and aviation industries replacing the heavier metals with the lighter one like aluminium and polymer therefore joining of these two materials is the requirement for the industries in the current time. A lot of studies have been already done to join these two materials in the lap, butt and t-joint configuration. Particular attention has been focused to macrostructural and microstructural evolution after welding, microhardness and tensile property. As the temperature is an important factor for both the polymer and aluminium due to difference in chemical and mechanical property, so FSW is a suitable technique compared to other fusion welding processes therefore improved joint property is expected. In the present study, process capability of FSW has been enlightened for joining aluminium-polymer materials for future prospective…
