  • Coaxial wire feed multi-laser metal deposition device
    Patent number: 11045906
    Abstract: A coaxial laser metal deposition head includes a wire guide and a plurality of laser optical units. The wire guide defines a wire guide axis. The laser optical units are distributed around the wire guide axis. Each of the laser optical units is connected to a separate laser and each defines a beam axis. The optical units are fixed relative to the wire guide and in a first condition are positioned to allow each of the beam axes to intersect the wire guide axis at a common point.
