Description
A friction stir welding (FSW) process based on the use of a self-reacting pin tool (SRPT) was developed for the joining of solid and hollow extrusions for aluminium railway car body structures; the mechanical properties of welded joints were investigated and process reliability aspects were examined. The workpiece material was an aluminium alloy A6N01S-T5 (Al, 0.4-0.8%Mg, 0.4-0.9%Si). The self-reacting FSW process was realised in a simple butt joint configuration. Finite element simulation was employed to model the temperature field, optimise process parameters (traverse speed, tool rotation speed and pinching force) and improve the SRPT probe design. Mechanical properties were characterised by tensile strength, fatigue strength and distortion measurements.
