Abstract
A method of controlling operation of an electron beam gun and wire feeder during deposition of pools of molten matter onto a substrate to form beads upon solidification of the molten matter. The method includes providing a substrate and a wire source. A molten pool of liquid phase metal is formed on the substrate by melting the wire utilizing an electron beam generated by an electron beam gun. The liquid metal solidifies into a solid phase. A controller utilizes data from a sensor to adjust a process perimeter based, at least in part, on data generated by the sensor.
