  • Lens to adapt laser intensity for uniform welding
    Patent number: 6713713
    Abstract: A laser welding lens assembly for welding a first article to a second article at a weld zone includes a laser source outputting a laser beam. An optical fiber is operably coupled to the laser source to receive and transmit the laser beam. A lens is then positioned to receive the laser beam from the optical fiber. The lens includes a contoured face that is shaped to refract the laser beam to produce a generally uniform temperature profile across the weld zone.
