The joining of dissimilar 6mm thickness plates AA6082 & AA5083 was carried out using the friction stir welding (FSW) technique. process parameters are optimized Taguchi L9 orthogonal design experiments. Where rotational speed (600, 900, 1200 rpm), travel (60, 90, 120 mm/min), and tilt angle (0, 1, 2◦ ) were taken into consideration. optimum determined with reference to tensile strength, yield s...

Samardžić, University of Osijek, Mechanical Engineering Faculty in Slavonski Brod, Croatia. Fundamental principles of friction welding of dissimilar steels (high speed and tempering steel) from the aspect of metallurgical and che...

The material flow and microstructural evolution in the friction stir welds of a 6061-Al alloy to itself and of a 6061-Al alloy to 2024-Al alloy plates of 12.7 mm in thickness were studied under different welding conditions. The results showed that plastic deformation, flow, and mechanical mixing of the material exhibit distinct asymmetry characteristics at both sides of the same and dissimilar ...

Friction Stir Welding (FSW) is a recently-developed technique where metals are joined together through mechanical stirring. FSW, often performed by robotic welders, is being used in an increasing number of industries such as aerospace, maritime and transportation. FSW has proven to be very effective and has replaced fusion welding and riveting in a number of manufacturing processes. In order to...
