Impact of Tool Rotational Speed and Welding Speed on Tensile Strength of Friction Stir Welded AA5083 Aluminum Alloy Joints

One of the most common materials in the fabrication sectors, especially in the auto sector, is Aluminum alloy. Owing to its low strength to weight ratio, it could be a good fit for a number of applications. The cold working procedure may strengthen the 5XXX series Aluminum alloy, which is not heat treatable and it is also challenging to fuse these alloys together using fusion welding processes. In Recent days, a solid-state welding procedure, Friction Stir Welding (FSW) is used to join this alloy. The impact of FSW process parameters on tensile strength of the joint is examined in this study. Based on the outcomes of the experiment, the highest tensile strength is observed at 900 RPM tool rotation, 100 mm/min welding speed, 1.5-degree tilt angle, and 3.0 tool diameter ratio. Superior strength (246 MPa) of this parameter over its competitors can be attributed to the balanced material flow and the formation of finer grains in the weld region.
