With regard to the development of friction stir shaping as a modified friction stir welding (FSW) process to maximise material flow within the weld zone and redistribute it into new shapes or features outside of or on top of the weld zone, an investigation is presented into proof of concept experiments and theories of material flow and tool design. The experimental set-up incorporated a small adjustable angle table bolted to the milling table. Multirun FSW was performed on Al 6061 aluminium alloy specimens at a rotational speed of 1400 rpm, traverse speed of 15.2 cm/min and tool tilt angle of 1.5 degrees. Based on the results, critical areas for optimisation and extension of the process were identified.
