ESABs friction stir welding robot Rosio™ enables flexible joining of complex structures, preferably in aluminium. the ability to perform welds in an arbitrary direction of a 3-dimensional workspace increases the possibilities of usage for new challenging FSW applications. The cell consists of an ABB IRB 7600 robot, modified for the purpose of FSW. The welding equipment is integrated in the mechanical structure of the robot without limiting the robot's standard working envelope. The robot's reachable workspace spans over 2.5 m, in which a down force of up to 13 kN may be applied during welding. Running on the latest state-of-the-art control system, an embedded force control solution allows in-contact motions with high accuracy.
