    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 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 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.

    摘要: Earth-boring tools such as, for example, earth-boring rotary drill bits include erosion-resistant structures disposed proximate areas of intersection between faces of the tools and fluid nozzle recesses or fluid passageways extending through the tools to the face. In some embodiments, such an erosion-resistant structure may comprise a mass of hardfacing material. In additional embodiments, such an erosion-resistant structure comprises an erosion-resistant insert. Methods of forming such earth-boring tools include providing erosion-resistant structures proximate intersections between the faces of the tools and fluid nozzle recesses or fluid passageways extending through the tools. Methods of repairing earth-boring tools include providing an annular-shaped, erosion-resistant structure over an eroded surface of a body of a previously used earth-boring tool proximate an intersection between an outer face of the body and an inner surface of the body.

    摘要: A drill bit for drilling a wellbore, the drill bit having a cutter which has tungsten carbide inserts and a spear point. The spear point has a neck that joins a smooth portion of the cutter and blades that extend from the neck and converge to an apex. The blades define valleys or spaces between them. A layer of hardfacing is applied to the entire spear point including the interim spaces and the neck.

    摘要: Methods of forming and repairing earth-boring tools include providing wear-resistant material over a temporary displacement member to form a cutting element pocket in a body and a depth-of-cut control feature using the wear-resistant material. In some embodiments, the wear-resistant material may comprise a particle-matrix composite material. For example, a hardfacing material may be built up over a temporary displacement member to form or repair a cutting element pocket and provide a depth-of-cut control feature. Earth-boring tools include a depth-of-cut control feature comprising a wear-resistant material. The depth-of-cut control feature is configured to limit a depth-of-cut of a cutting element secured within a cutting element pocket partially defined by at least one surface of the depth-of-cut control feature. Intermediate structures formed during fabrication of earth-boring tools include a depth-of-cut control feature extending over a temporary displacement member.
