There has been growing interest in the heavy metal industries with the recent progress in the friction stir welding (FSW) of thick aluminium welds. However, despite the recent progress in this area, many challenges still need to be overcome before it comes to full scale industrial use. With an increased thickness, the requirements of a higher power, load bearing ability of the tool, axial load, and welding and clamping forces make the task more challenging in terms of the selection of the process control parameters, FSW machine, tool material technology and design and the weld thermal management. Therefore, this paper describes the main challenges related to the FSW of thick aluminium plates as well as provide the perspectives to the researchers and industries to evaluate the changes to the welding tool design and operating parameters, extension of process window and suggest new improvements to the process.
