Off-line path programming for three-dimensional robotic friction stir welding based on Bézier curves Article dans une revue avec comité de lecture(Emerald, 2018)Robotic friction stir welding (RFSW) is an innovative process which enables solid-state welding of aluminum parts using robots. A major drawback of this process is that the robot joints undergo elastic deformation during ...
