Abstract

Friction stir welding process (FSW) is an emerging solid state joining process in which the material that is being welded does not melt and recast. The FSW process and tool parameters play a major role in deciding the joint characteristics.  Therefore, mechanical properties should be controlled to obtain good welded joints.  In this investigation, an attempt has been made to understand the effect of heat input on microstructure and mechanical properties of friction stir welded AA1100 aluminium joints. The joints are fabricated using different D/d ratio’s (1.8, 2.4, 3, 3.6, and 4.2) and respect heat inputs (0.568, 0.758, 0.947, 1.137 and 1.326 kJ/mm). The joints fabricated with a D/d ratio of 3 (0.947kJ/mm) has yield superior mechanical properties.
