A welding window device includes an elongated body that defines a welding cavity that extends through the body from a top side to a bottom side. The welding cavity is framed by an inlet end, an outlet end, and lateral sides of the body. The body includes one or more gas channels inwardly extending through one or more of the first lateral side or the second lateral side from an inlet opening in the inlet end toward the outlet end of the body. The gas channels include nozzle openings inwardly oriented toward the welding cavity. The gas channels are positioned in the body to direct a gas into the welding cavity during welding of other bodies together within the welding cavity.

A new electrospark deposition (ESD) method and related system are provided in the present invention based on the use of a magnetized electrode, namely magnetic-aided ESD (M-ESD). In particular, the present invention uses a magnetized electrode (either magnetized by an electro-magnet or being a permanent magnet) to attract fine coating powders at the tip thereof which acts as a soft brush to coat on intricate surface profiles. Accordingly, the method of the present invention is able to provide a soft contact between the magnetized anode and the workpiece to be coated or manipulated. The present invention is useful in various surface engineering applications in the fields of aeronautical (e.g. restoration and repair of damaged aircraft turbine blades), nuclear reactors, military engineering, and in medical industries. As compared to conventional ESD, the present invention can address complicated surface geometries and internal surfaces while the cost can be significantly lowered by using inexpensive components and simplified method steps.

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.
