    摘要: A method of forming at least a portion of an earth-boring tool using an electronic representation of at least one geometric feature of at least a component of an earth-boring tool stored in memory accessible by a processor operatively connected to a multi-axis positioning system, a direct metal deposition apparatus, and a material removal apparatus. The processor generates a deposition path for the direct metal deposition apparatus is based at least in part on the electronic representation of the at least one geometric feature of the at least a component of the earth-boring tool. The direct metal deposition tool is operated according to the generated deposition path to deposit metal material on an earth-boring tool component coupled to the multi-axis positioning system to at least partially form the at least one geometric feature of the earth-boring tool. Methods also include methods of repairing earth-boring tools.

    摘要: A method of forming an earth-boring tool includes forming a tool body including at least one inverted cutting element pocket, at least a portion of the at least one inverted cutting element pocket having a profile substantially matching a profile of an actual cutting element to be secured within a cutting element pocket to be formed by subsequently machining the at least one inverted cutting element pocket. Hardfacing material may be applied to portions of the tool body. The actual cutting element pocket is formed by removing material of the tool body within the at least one inverted cutting element pocket subsequent to applying the hardfacing material to portions of the tool body. A cutting element is affixed within the actual cutting element pocket.

    摘要: Improvements relating to a mechanically lined pipe A reelable mechanically lined pipe (MLP) having a metallic outer pipe (4, 42) and a metallic inner liner (6, 44), wherein the inner liner (6, 44) is secured to the outer pipe (4, 42) by one or more welds (46) extending longitudinally along the MLP. Longitudinal welds (46) are more efficient in pipeline manufacture, and in preventing 'wrinkling' of the inner liner (6, 44) when the MLP undergoes bending, in particular spooling the MLP onto and off a reel (10). Alternatively, any wrinkles formed are sufficiently minor or small that they can be reduced or removed once the MLP is installed on a seabed and after a hydrotesting step.
