Aspects of the disclosure are directed to processing a component. A first coating is removed from a substrate of the component, the substrate including a first hole. Subsequent to removing the first coating from the substrate, a second coating is applied to the substrate, where a portion of the second coating at least partially blocks the first hole. Subsequent to applying the second coating to the substrate, the portion of the second coating is removed to generate a second hole through the second coating. The removal of the portion of the second coating creates a bore in the second coating that provides a clearance from an edge of the first hole on a surface of the substrate that interfaces to the second coating.

A method of forming a planetary carrier assembly is disclosed herein. In one aspect, the method includes providing a first carrier plate and a second carrier plate. The first carrier plate has a first body portion, and the second carrier plate has a second body portion including a plurality of legs. The method includes forming at least one staking element on an axial end of at least one of the plurality of legs. The method includes fixing the first carrier plate and the second carrier plate to each other via application of an axial load such that the at least one staking element on the at least one of the plurality of legs digs into the first carrier plate.

Device and method for laser welding around a circumference of a workpiece. A fixed, non-movable unitary optical reflector has a pair of optical reflecting surface portions on a first side surface and a second side surface, respectively, arranged at an obtuse angle relative to each other. A workpiece is fixed in an assembly having the reflector. During setup, the vertical distance is adjusted between the reflector and workpiece along an axis that is transverse to a longitudinal axis thereof without any adjustment of the reflecting surfaces. The first and second side surfaces define a curve that is transverse to the longitudinal axis. Once setup has been completed, a laser beam is directed so that it moves along the optical reflector to thereby produce a 360 degree circumferential weld around the workpiece. Another assembly is provided to change the laser beam direction multiple times to irradiate a circumference of a fixed workpiece from a fixed laser source.

A system for welding two pipes includes a first pipe clamp, a second pipe clamp, a weld torch, an inspection detector, a motor, one or more processors, and a grinder. The weld torch is configured to create a weld joint between the pipes at an interface region between the pipes. The inspection detector is configured to emit an inspection beam of radiation. The motor is operatively associated with the inspection detector to direct the inspection beam of radiation along the weld joint between the pipes. The one or more processors are operatively associated with the inspection detector to determine a profile of the weld joint between the pipes. The grinder is configured to grind at least a portion of the weld joint between the pipes based on the profile of the weld joint between the pipes.

Disclosed herein are various technologies pertinent to rocket engines, including injector, thrust chamber, and electrical turbopump devices that may be combined to provide a more efficient rocket engine. The thrust chamber may be coupled with an injector having a circular array of support columns supporting a distribution system. Liquid may be flowed from the distribution system, through the support columns, and into a combustion chamber of the thrust chamber.

Disclosed herein are various technologies pertinent to rocket engines, including injector, thrust chamber, and electrical turbopump devices that may be combined to provide a more efficient rocket engine. The electrical turbopump impeller includes a coolant bypass port fluidically connected with a coolant passage that passes through the impeller central hub and allows some of the propellant that is acted on by the impeller to bypass the impeller outlet and instead be flowed into the electrical turbopump housing so that the diverted propellant may be used to cool the various components housed within the housing such as the electric motor bearings, stator, rotor, and electronics.

A resin pipe 30 and a resin member 31 are fixed to a setting portion 5 provided on the front side of a base 6, and a timing pulley 13 which is provided on the back side of the base 6 and to which a light emission unit 3 is attached is rotated. As a result, the light emission unit 3 applies laser light 20 to a junction 32 between the resin pipe 30 and the resin member 31 while revolving around the junction 32. This makes it easy to fuse and join the entire outer circumferential surface of the resin pipe 30 with the entire inner circumferential surface of the resin member 31, which are variously shaped and sized.
