This programme seeks to determine the defect and void formation process for bobbin friction stir welding (BFSW). There are a number of projects, each of which is a separate thesis topic. This has been a particularly productive area for research and publications. Interested students are welcome to contact me.
 Process parameters - we have worked out which tool features and process settings to use for aluminium 6082-T6. This work was done by Dr Kamil Sued for his PhD. We are open to having another project in this area. Involves DoE, production engineering, and experimentation.
 Microstructure of the weld - we now know how to etch 6082-T6, and how the internal flow affects the microstructure. This work has been done by Abbas Tamadon for a PhD thesis. We are open to having another project in this area. Involves materials science.
and many more
 Internal flow features. We have worked out a qualitative description of the flow. This now needs a numerical model to be developed using CFD and FEA. Interested?
