Patent ID: 8399792

Claim:
A welding device for depositing material on the surface of an associated workpiece, comprising: an electrode head adapted to concurrently house an array of associated multiple, continuous-feed electrodes in a spaced apart configuration for concurrently depositing material on the surface of the associated workpiece, wherein said array of associated multiple, continuous feed electrodes includes an electrode near a center of said electrode head and plural electrodes located outward of said electrode near said center of said electrode head, wherein said electrodes located outward of said electrode near said center of said electrode head have a diameter greater than said electrode near said center of said electrode head; wherein the electrode head is actuatable through a welding trajectory; a welding power source adapted to provide power for simultaneously establishing a welding arc between each of the associated multiple, continuous-feed electrodes and the associated workpiece; and, means for concurrently driving the array of associated multiple, continuous-feed electrodes through the electrode head.
