The use of matching tapers to provide a hot friction drive coupling for composite refractory tools for conventional and bobbin friction stir welding of 12% chromium alloy steel is described. The feasibility of using self-reacting (Bobbin) friction stir welding for steel has been demonstrated and the resulting microstructures have been evaluated.
