Open the CIPO recordAbstract From the Canadian patent
A plurality of stretches (T) of laser weld are executed on a structure to be welded by means of a device (16) for focusing and orientation of the laser beam which is associated to a component element (13) of a manipulator robot (1). The focusing head is kept in the proximity of but not closely adjacent to, the different areas to be welded and can consequently follow a simplified path (R) whilst the device (16) for orientation of the laser beam aims the latter on the different areas of the structure to be welded so that the speed of travel of the laser beam spot along the longitudinal direction of the weld stretch is independent from the speed of travel of the robot end element.
