A laser cladding system includes a laser apparatus, a chamber, and a pump system. The laser apparatus is configured to generate a laser beam. The chamber includes an interior surface that defines a cladding area comprising a sealed volume. The chamber includes a window that is made from a laser-transparent material and is configured to allow the laser beam to pass therethrough into the cladding area. The pump system has a port in communication with the cladding area. The pump system is configured to selectively generate a vacuum pressure within the cladding area sufficient to evacuate gas from within the cladding area out through the port. The laser apparatus includes a laser head from which the laser beam is emitted and a robotic laser motion system configured to selectively move the laser head such that the laser beam moves relative to a reference point within the chamber.
