摘要： Earth-boring tools include wear-resistant materials disposed in at least one recess formed in an exterior surface of a body thereof. Exposed surfaces of the wear-resistant material are substantially level with exterior surfaces of the body adjacent the wear-resistant material. In some embodiments, recesses may be formed in formation-engaging surfaces of blades of earth-boring rotary tools, adjacent one or more inserts secured to bodies of earth-boring tools, or adjacent one or more cutting elements secured to bodies of earth-boring tools. Methods of forming earth-boring tools include filling one or more recesses formed in an exterior surface of a body with wear-resistant material and causing exposed surfaces of the wear-resistant material to be substantially level with the exterior surface of the body.

摘要： The present invention relates to a system and method for automated or “robotic” application of hardfacing to the surface of a steel-toothed cutter of a standard earth-boring rock bit or a hybrid-type rock bit. In particular, the system incorporates a grounded adapter plate and chuck mounted to a robotic arm for grasping and manipulating a rock bit cutter, particularly a hybrid rock bit cutter, beneath an electrical or photonic energy welding source, such as a plasma arc welding torch manipulated by a positioner. In this configuration, the torch is positioned substantially vertically and oscillated along a horizontal axis as the cutter is manipulated relative along a target path for the distribution of hardfacing. Moving the cutter beneath the torch allows more areas of more teeth to be overlayed, and allows superior placement for operational feedback, such as automatic positioning and parameter correction. In the preferred embodiment, sensors provide data to the control system for identification, positioning, welding program selection, and welding program correction. The control system, aided by data from the sensors, manipulates the robotically held cutter while controlling the operation and oscillation of the torch. These systems and methods can be applied to hardfacing steel teeth of the rolling cutters of both standard tri-cone or di-cone type rolling cone bits, as well as to hybrid-type earth boring drill bits.
