Abstract: A measurement device provides coordinates for a specified location and position on the exterior surface of a vessel, including a base adapted to contact the exterior surface of the vessel; a rail extending upwardly from the base, the rail including a measurement scale; a head slidably supported by the rail; the head including a clamping mechanism used to releasably secure the head to the rail; and a laser carried by the head for projecting an image on the exterior surface of the vessel. The device quickly measures both the radial position and the angular position of an indicated location relative to the axis of the nozzle, and the skew of a transducer probe which provided the indicated location.

Abstract: A method of repairing a substrate includes the step of excavating a well in the substrate with an electrical discharge machining operation. A wire is then delivered to the well. Simultaneously, laser energy is routed to the well such that the laser energy intersects with the wire to produce a reconstruction weld in the well. A tool delivery system with an electrical discharge machining tool head and a reconstruction welding tool head is used to perform the excavation and welding operations.

Abstract: A laser welding apparatus for clad welding the interior surface of a tube includes a rotating sleeve that encloses a fiber optic cable. A stationary laser generates light energy for the welding operations performed by the rotating sleeve. An optical coupler is positioned between the stationary laser and the rotating sleeve. A fixed optical assembly of the optical coupler receives light energy from the stationary laser and produces collimated and focused light energy. A rotating cable interface assembly of the optical coupler receives the collimated and focused light energy from the fixed optical assembly and applies it to the fiber optic cable of the rotating sleeve, which delivers the light energy to the interior surface of a tube so that it may be used to produce a clad weld. The fixed optical assembly includes axial and concentric alignment devices.
