The comparative method i.Friction stir welding (FSW) is a widely used solid state joining process for soft materials such as aluminium alloys because it avoids many of the common problems of fusion welding. Nov 14,  · In this paper, a three dimension heat source is developed in laser heated friction stir welding.

The model was calculated by CFD software FLUENT, and the temperature field and flow field of the welding are obtained. This research paper deals with the characterization of friction stir welded dissimilar Aluminium alloys AA and AA The coupons of above metals were friction - stir welded using cylindrical pin tool using at constant speed of rpm and at two different feed rates of 28 and 20 mm/min.

Macrographs showed proper mixing due to effective stirring of cylindrical tool pin while keeping the. Friction stir welding (FSW) is a solid-state joining process that uses a non-consumable tool to join two facing workpieces without melting the workpiece material.

Heat is generated by friction between the rotating tool and the workpiece material, which leads to a softened region near the FSW tool.

The Vanderbilt University Welding Automation Laboratory (VUWAL) has spent more than three decades developing control systems for advanced robotic welding and joining processes.

Most recently the efforts of the lab have largely been focused on process optimization and control for friction stir welding (FSW). Friction stir welding differs from competing processes such as arc and laser welding, since these use an external heat source of specified power, whereas in FSW the joining process itself generates the heat.
