The Feasibility Of Augmenting A Fixed-Gap Bobbin Friction Stir Welding Tool With Cutters To Join Enclosed Castings, Adam Baxter Christensen

Theses and Dissertations

Bobbin Friction Stir Welding (BFSW) is a new application of Friction Stir Welding (FSW) that can be used to join materials together with little to no axial forces. This eliminates the need of a backplate or anvil needed to apply counter pressure against the tool. The applications of BFSW are growing every day. This new technology is helping the automotive industry and many other industries join materials more effectively and efficiently. This technology can be used to join materials with high strength to weight ratios to make cars lighter to increase fuel efficiency. This will also greatly reduce the cost …
