Embodiments of the present disclosure relate generally to an apparatus and method for treating a rotatable component. An apparatus according to the present disclosure can include: a sliding engagement member configured to slidably engage a portion of a rotating component that is temporarily stationary; and a tool engaging member for positioning a machining tool relative to the rotating component to machine a surface of the rotating component, wherein the tool engaging member is rotatable to one of a plurality of angles relative to the sliding engagement member.

A repair method for repairing an assembly including a main body and an old reinforcement, the assembly including an initial hole passing through the old reinforcement and at least a portion of the main body, the method including removing the old reinforcement; positioning a plug in the initial hole in the main body; fastening a new reinforcement on the main body, the new reinforcement covering the plug; and forming a new hole passing through the new reinforcement and at least a portion of the main body.

Example systems may include an energy source, a material delivery device, and a computing device. The computing device, based on a target height of a layer deposited on a component by directed energy deposition, may control an energy source directed at a component and may control a material delivery device. Controlling the energy source may include advancing an energy beam along a first path to form an advancing molten pool on the component. Controlling the material delivery device may include delivering a material to the advancing molten pool. The material may combine with the advancing molten pool to form a first raised track having an actual height. The layer may include the first raised track. A deposited region of the component may include the layer. The actual height may affect a resultant microstructure within the deposited region.

A structural element for repairing a damaged component comprising a shaped cavity configured to receive the damaged component and a repair material, the shaped cavity comprising a material having a first melting point and the repair material comprising a material having a second melting point that is lower than the first melting point. The shaped cavity may comprise a preform for the damaged component. The preform may comprise a mold configured to reconstruct the shape of the damaged component. The repair material may comprise a first material and a second material, the second material having a melting point that is lower than the first material. The repair material may comprise a Nickel-Boron composition. The repair material may have a melting point that is approximately 40 degrees Fahrenheit lower than the melting point of the damaged component.

The present disclosure is directed to a system and method for repairing an abradable material coated on a casing of a gas turbine engine. The system includes an articulating guide configured to fit into an access port of the gas turbine engine. Further, the articulating guide has a proximal end and a distal end. The system also includes a repair tool configured at a distal end of the articulating guide. The repair tool includes a body having a proximal end and a shaped distal end, with the shaped distal end extending away from the body. Thus, the shaped distal body is configured to trench out an area of the abradable material comprising a defect. The system also includes a filler material for filling the trenched out area.

A mobile pipe rack workstation for inspecting and repairing pipe materials, a “Pipe Station.” By folding the pipe station's load/unload arms, removing any tool's from the tool mount and lowering the gantry by retracting the risers; the pipe station is transportable on public roadways without permitting, escorting, or special signage required for oversized loads.

A method is provided for servicing a jointed rotor blade of a wind turbine. The jointed rotor blade is positioned in a six o'clock position and a blade tip support element is secured to a tip section of the jointed rotor blade. A lift-support element is secured at a mounting location above the blade tip support element. A lifting line is coupled between the lift-support element and the blade tip support element. The tip section is separated from the root section of the jointed rotor blade such that the tip section is suspended above a support surface of the wind turbine via the blade tip support element and the lifting line. The tip section of the jointed rotor blade is serviced.

A method for remotely stopping a crack in a component of a gas turbine engine is provided. The method can include inserting an integrated repair interface attached to a cable delivery system within a gas turbine engine; positioning the tip adjacent to a defect within a surface of the component; temporarily attaching the tip adjacent to the defect within the surface on the component; supplying a new material to the area to fill the defect; and heating the new material to fuse the new material to the component within the defect.
