摘要： Apparatus is disclosed for aligning a laser beam used to perform laser machining operations. The aligning apparatus of this invention is used with laser machining apparatus comprising a laser for emitting a laser beam along a path and a laser lens assembly disposed within the path and movable along an axis for variably focusing the laser beam at a plurality of different focal spots corresponding to the plurality of laser machining operations. The alignment apparatus takes the form of an adjustable mirror, which is disposed to intercept the laser beam and to align at least a portion of the path with the axis of the laser lens assembly, whereby the lateral displacement of each of said plurality of focal spots from the axis is reduced as the laser focusing assembly is moved along its axis.

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： A method for welding a sleeve within a tube of a steam generator, the sleeve being in close contact with the tube. A welding head of a weld head apparatus is positioned within the tube at a predetermined weld site, a laser beam is directed to the welding head, the beam is focused with a focusing means, the focused laser beam is reflected with a welding mirror means into contact with a portion of the sleeve to be welded to the tube, the welding mirror means is maintained a predetermined focal distance from the inside surface of the sleeve, and the welding head is rotated to complete a weld fusion path about the inner periphery of the sleeve. Shielding gas is used to shield the weld site. A robotic arm positions the weld head apparatus within the steam generator. At each end of the sleeve, multiple discrete weld paths or a continuous helical multiple weld path are welded. The sleeve is preferably welded to the tube along the weld path with a fusion width at the interface between the sleeve and tube of at least 0.045 inches and the tube is penetrated to a depth of at least 0.25 inches. The laser delivers 500 to 700 watts to the weld area.

摘要： A method and apparatus for aligning laser cavity and transport optics with one or more targets is disclosed. An alignment beam is deflected from its initial path and is rotated about the alignment axis in an annular sweep. Detectors circumferentially located about a desired point located relative to the target are responsive to the intensity of the rotatig alignment beam for producing corresponding outputs. The cavity optics and transport optics may be adjusted relative to the target so that the output of the detectors are the same thereby assuring that the various respective optics are aligned with the target.

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.
