Description
Experiments were undertaken to investigate the evolution of welding forces and torque generated during robotic friction stir welding of circular and semicircular butt welds in 6082-T651 aluminium alloy plates (thickness 6 mm). Welding was performed in an I-Stir 10 MTS gantry machine at a rotational speed of 900 or 1100 rpm and a travel speed of 450 or 650 mm/min. A parametric experimental study was conducted in which the parameters were the curvature of the weld seam and the position of the advancing side according to this curvature. The applicability of a statistical model describing welding forces and torque as a function of process parameters developed for straight line conditions was tested for different weld path geometries.
