Abstract
device for remote laser welding of metal sheet structures comprises an anthropomorphous robot onto whose wrist is mounted an accessory device carrying a focusing head for the laser beam coming from a laser source, as well as means for oscillating the pointing direction of the focused laser beam around one oscillation axis. During welding the robot shifts the accessory device along a given trajectory and at a given speed, while the pointing direction of the focused beam is oscillated to as to allow the area of structure that is lighted by the laser beam to shift at a speed and/or along a trajectory not depending directly on the shifting trajectory and speed of the accessory device carried by the robot.
