Description
A report is presented into the "RoboFSW" project, intended to qualify a high payload articulated arm robot for friction stir welding (FSW); hardware modification and control system integration are described and 3D FSW capability is reported for circular bead-on-plate welding. FSW machine types are summarised and characteristics of the "KUKA KR500" robot are outlined. Engine current measurements and tool deviations caused by process forces are discussed. FSW butt joints in AA 6156-T6 aluminium alloys were produced by the robot in the end-effector position, and were characterised by microstructural observations, microhardness measurements and tensile tests. A force measurement system and a convex-concave shaped device are described also.
