                 alloys may be joined by the process. A suitable material for a rotating tool
                 to permit friction stir welding of steel has yet to be developed.
                   Typical applications of friction stir welding are the construction of alu-
                 minium alloy deck panels for high speed craft from extruded sections and
                 aluminium alloy honeycomb panels for passenger ship cabin bulkheads.
