Description
The development of an industrialised robot for friction stir welding (FSW) for aluminium alloys is described. The influence of the main processing parameters, plunging and rotational speeds, on FSW performance and efficiency were investigated. The qualification procedure was performed on 5083-H111, 5 mm thickness. The interactions between the tool and material generated during the welding operation were determined. The design of the rotating tool, comprising a shoulder and pin, is discussed. The force range and torque diagrams were established for the processing parameters, from which a suitable method and equipment for FSW were determined. Production testing covered variations including gaps, mismatch and material thicknesses. Weld repair procedures were also studied.
