Claim:
1. A system for depositing hardfacing material on at least a portion of an earth-boring tool, comprising: a torch positioner comprising a hardfacing torch movable in at least a first plane and a second, perpendicular plane, the hardfacing torch being configured to deposit hardfacing on at least a portion of an earth-boring tool; a workpiece positioner comprising a holder configured to support the at least a portion of the earth-boring tool in the holder, the holder being movable in at least a third plane parallel to the second plane; at least one sensor configured to determine a location of a surface of the at least a portion of the earth-boring tool supported by the workpiece positioner; and a programmable control system operatively connected to the torch positioner, the workpiece positioner, and the at least one sensor, the programmable control system being programmed to cause the torch positioner to oscillate the hardfacing torch in the second plane while selectively causing the workpiece positioner to move the holder in the third plane and causing the torch to deposit hardfacing material on the surface of the at least a portion of the earth-boring tool.
