Description
The main factors to be considered in the automation and robotisation of friction stir welding (FSW) and the production of one-, two- and three-dimensional welds were identified. A FSW robotic cell was developed and force control algorithms were defined and implemented in the robot controller. Bending and traction tests were performed on linear welds made in 6061-T6 AlMgSi alloy (3 and 6 mm thickness) using the articulated robot arm. The use of the robot to weld corners and corner areas was also evaluated. After results confirmed the robustness of the force control algorithms to weld 3D trajectories, the robot was then assessed for the production of 3D welds. Bending and traction test data are presented and compared with those for linear weld results.
