Description
The stationary shoulder technique was applied to the self reacting pin tool (SRPT) for friction stir welding (FSW) of high quality aluminium alloy railway car body structures in order to enhance the appearance of no coating side structures constructed by hollow extrusions. A finite element method procedure was developed to optimise SRPT tool design and the process window. Experiments involved fabrication of butt joints in A6005C alloy (Al, 0.4-0.8%Mg, 0.4-0.9%Si) using a prototype stationary shoulder SRPT design. The surface appearance and cross sectional microstructure of the joint were studied. Mechanical properties were characterised by tensile strength and fatigue strength measurements. Construction of a semi monocoque (fuselage) structure by FSW and feasibility trial results for lap joints welded by the stationary shoulder tool are discussed.
