Abstract
Friction stir welding (FSW) is a relatively new welding process and its comprehensive understanding is still developing. While the process is commercially used for aluminum and other soft alloys, its commercial application for the welding of hard alloys will require development of cost-effective and durable tools. Here we review the recent progress made in numerical modeling heat transfer and material flow with particular emphasis on optimizing tool dimensions and selection of welding conditions for maximizing tool durability. 22 Ref., 2 Tables, 6 Figures.


Keywords: friction stir welding, numerical modeling, heat transfer, material flow, welding conditions, tool durability
