  A Review of Recent Advancements in the Field of Friction Stir Welding of Dissimilar Joints Made of Aluminium and Magnesium

  By P J Lokesh Kumar, S Shankaranarayanan, C Jayabalan, S D Sekar, K Sengottaiyan, R Suresh Kumar

  Abstract: Friction stir welding (FSW) stands at the forefront of welding technology, offering a promising avenue for joining dissimilar metals like aluminum and magnesium. These metals, renowned for their exceptional properties such as ductility, thermal conductivity, low density, and impressive weight-to-strength ratios, find wide utility across numerous industrial sectors. However, traditional fusion welding methods often struggle to effectively join aluminum and magnesium due to their disparate physical and chemical characteristics. FSW …

  Impact of Tool rotating speeds on the Mechanical characteristics of dissimilar friction stir-welded AZ80A-Mg – AA6061-Al joints

  By P J Lokesh Kumar, P Sevvel, S Shankaranarayanan, C Jayabalan, S D Sekar, K Sengottaiyan

  Abstract: In this investigation, separate AA6061-Al and AZ80A-Mg alloy plates were effectively joined through stir welding with friction. We looked closely at the weld joints' characteristics, especially their mechanical aspects. In the experiment, here were multiple tool rotating rates (rpm) of 800, 1000, 1200, 1400, and 1600 used. A cylindrical pin-equipped tool featuring a tapered profile was utilized, inserted into the AA6061 alloy plate is offset by 0.5 mm, while maintaining …
