摘要： A system is disclosed for aligning a high-power laser apparatus to transmit a high-power beam along an optimum beam path to an adjustable remote beam receiver and for aligning the beam receiver for optimum reception of the high-power beam. A low-power visible laser is directed along the path to be followed by the high-power laser and a viewer such as a video camera is used for rough alignment. A pellicle, a partially reflecting mirror, and three low-power beam detectors are used with the low-power laser to align the beam transmitter with the beam receiver. Alignment of the beam receiver with the beam transmitter is checked by a high-power laser beam alignment checking system. This alignment checking system employs an annular beam detector mounted near the beam transmitter and a second beam detector mounted near the beam receiver. A beam intensity reducer is used to reduce the intensity of the high-power beam for use in alignment since prolonged direct contact by a full-power beam with the detectors would damage the detectors. A method for aligning the laser beam transmitter and receiver is also described.

摘要： A laser welding system is disclosed in which a high power laser produces the laser beam for delivery to a weld site. A transmitter is optically coupled to the laser and directs the laser beam to a spatially separated receiver. The receiver has an input alignable for receiving the directed laser beam and including optics for delivering the laser beam to the weld site. A pair of directable beam deflectors are employed for aligning the transmitter and the receiver. A pair of steering deflectors introduce the laser beam into the transmitter. A selectable mounting allows the laser to be secured at various orientations relative to the steering mirrors and the weld site. The transmitter and the receiver each have a detector positioned for receiving an alignment laser beam at a point which indicates alignment. The transmitter and the receiver include steppable drives for positioning their respective deflectors. The alignment laser is aligned at a starting block on the receiver detector and the transmitter detector. The steppable drives are each driven away from the starting block by an amount sufficient to eliminate backlash when the drives are reversed. Each steppable drive is then reversed and driven in one direction to bring the alignment laser beam back to the starting block and thereafter into the alignment position in a series of sequential alignment steps.

摘要： A laser welding head for welding a sleeve within a tube by fusing the interface between the sleeve and tube with a laser beam. The laser welding head has a cylindrical housing adapted to be inserted inside of the sleeve, a focusing lens for focusing a laser beam transmitted through the housing, and a welding mirror for directing the focused beam out of the housing and into contact with the sleeve. The welding mirror is maintained a predetermined distance from the inside surface of the sleeve and a motor and drive assembly are used to rotate the welding head within the sleeve. Shield gas is supplied to the welding head and passes about the periphery of the focusing lens for cooling the focusing lens and the welding mirror before being discharged into contact with the weld area. A recessed aperture is provided within the discharge outlet to prevent molten material from the weld site from splattering into the housing and onto the mirror or lens. Multiple pass welds are preferred for attaching each end of the sleeve to the tube with the preferred weld paths being either multiple discrete weld paths or continuous overlapping helical weld paths at each end of the sleeve.

摘要： Apparatus and method for remotely positioning a probe, such as an examination or repair probe, in a tubular member. The tubular member may be a nuclear steam generator heat transfer tube to be examined or repaired by the probe. The probe is connected to a conduit which supports the probe as the probe advances along the inner diameter of the tube to the location of the tube requiring examination or repair. The conduit has a portion thereof wound about a take-up reel. As the probe and conduit advance in the tube, it unwinds from about the take-up reel. However, as the conduit unwinds from about the take-up reel, it may tend to develop a "kinked", twisted or contorted region therein inducing torsional stress in the conduit. Such torsional stress may be severe enough to break the conduit. The apparatus of the invention includes a gripper capable of gripping the conduit and also includes a rotator connected to the gripper for rotating both the gripper and the conduit gripped thereby. As the rotator rotates the gripper, the gripper and a portion of the conduit simultaneously rotate for removing the contorted region, so that the torsional stress induced in the conduit is relieved.
摘要翻译：用于将诸如检查或修复探针的探针远程定位在管状构件中的装置和方法。管状构件可以是通过探针检查或修理的核蒸汽发生器传热管。当探头沿着管的内径前进到需要检查或修理的管的位置时，探针连接到支撑探针的导管。导管的一部分缠绕在卷取卷轴上。当探头和导管在管中推进时，它从卷绕卷轴上卷绕。然而，当导管从卷绕卷轴周围展开时，它可能倾向于在其中形成“扭结的”，扭曲或扭转的区域，从而导致管道中的扭转应力。这种扭转应力可能足够严重以破坏导管。本发明的装置包括能抓握导管的夹持器，并且还包括连接到夹持器的旋转器，用于使夹持器和由此夹持的导管旋转。当旋转器旋转夹持器时，夹持器和导管的一部分同时旋转以除去扭曲的区域，使得导管中引起的扭转应力得以缓解。
