摘要： An earth boring bit has a steel body having at least one leg with a depending bearing pin. A cone having cutting elements is rotatably mounted to the bearing pin. A ball plug weld is on the outer surface of the leg. A layer of hardfacing applied to part of the outer surface of the leg, the hardfacing having carbide particles in a matrix. A corrosion resistant coating containing at least 50% nickel is formed on parts of the outer surface of the leg that are free of the layer of hardfacing both above and below the ball plug weld.

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.
