An upstream rail of a turbine engine turbine casing, which includes a casing body extending along a longitudinal axis, includes a base including a radial face, extending substantially radially from the casing body, a plate including an upper face, extending substantially along the longitudinal axis, a connection portion between the base and the plate, including a concave face connecting the radial and upper faces, the concave and radial faces extending on either side of an edge. The upstream rail is repaired through a method including covering a surface with a solder, the surface including the upper and concave faces such that the solder extends until the edge, and machining the covered surface, in a single action, in a direction toward the radial face, so as to reshape the surface, wherein the machining of the covered surface is performed on a portion of the radial face.

Methods of repairing a periphery of a threaded hole of a part are provided. An embodiment of the method includes adding material to a region of the part including on a periphery of the threaded hole. New threads are formed in the added material. The new threads are continuous with existing threads formed in the hole.

Various methods of hardbanding an apparatus are described. In one aspect of the invention an improved method of re-applying a hardbanding alloy to worn tool joints of a previously hardbanded drill pipe results in preservation of the metallurgical properties of the drill pipe and preservation of the internal polymer coating that lines the drill pipe. A method for applying hardbanding includes arc welding a consumable metal welding wire to a tool joint having a surface temperature that ranges from about 50° F. to about 170° F. and the arc welding power supply utilizes DC current. The method herein produces a hardbanded tool joint comprising a heat affected zone (HAZ) of a based metal having a Rockwell hardness of 40 Rc or less.

A weld overlay machine assembly includes a carriage to support a hinged index bar and a wire feed assembly. The index bar has an auto height control unit and an index assembly to locate the position of a weld torch relative to the index bar. The assembly is configured to adjust the index bar to interior contours of the vessel while applying a layer of overlay material to a surface therein. The assembly runs along a track in the interior of the vessel. The assembly is configured to transition from sides of the vessel to that of the top or bottom domes wherein the curve of the domes are perpendicular to that of the radial sides. This transition is done without the need to add or remove components to the assembly. This is accomplished by providing the pivoting of the index bar relative to the track.

A hardfacing metal composition and method of restoring worn work string tubing by application of a hardfacing metal to the worn regions of the work string tubing.

The invention provides a pneumatic conveying system having a series of supply lines with at least portions of the lines being wear resistant to extend the useful lifespan of an agricultural product delivery applicator. The wear resistant supply line(s) may be made from a hard material and have a curve(s) defined by angled or mitered segments that are welded or otherwise joined to collectively provide the curve(s) The wear resistant supply lines may be at least partially reinforced by way of, for example, welded or other build up wear resistant material(s) at high wear zones of the supply lines.

Methods of repairing a periphery of a threaded hole of a part are provided. An embodiment of the method includes adding material to a region of the part including on a periphery of the threaded hole. New threads are formed in the added material. The new threads are continuous with existing threads formed in the hole.

A steel pipe is for drilling, exploiting hydrocarbon wells, transporting petrol and gas, carbon capture or geothermal energy. The steel pipe includes at least one male or female insert and a metal body. The insert includes at least a first thread axis, at least one toric or frusto-conical sealing surface, a threaded portion and a non-threaded portion connected to the metal body. The metal body is made entirely by additive manufacturing and the insert includes an anchoring profile arranged so as to adhere the additive material of the metal body.

A method of hardfacing a metal component includes welding a surface area of the metal component using a Cold Metal Transfer (CMT) process. The method of hardfacing the metal component includes performing the CMT welding process in a weaving pattern over the surface area of the component. A consumable, low carbon steel wire electrode is used in the CMT process.

Apparatuses and methods for repairing a defect in a nuclear reactor are provided. The apparatus includes a body for insertion in a tubular structure, the body includes: an end effector having a weld torch operable to deposit weld material by forming molten weld droplets and depositing the weld droplets the tubular structure. A drive unit includes a brace for selectively anchoring against said tubular structure; at least one linear actuator for moving the apparatus relative to the brace; and a rotational actuator coupled to rotate the weld torch. The method includes inserting a repair apparatus into tubular structure of the nuclear reactor; moving the repair apparatus to a defect location; depositing a protective weld layer over the defect by sequentially depositing weld droplets atop a weld pool on the tubular structure, wherein the protective weld layer bonds to the tubular structure surrounding the defect.
