摘要:
The invention relates to a tool (10) for welding a mounting bracket to a tube of a tank and comprising tube-grasping means (16, 18) that clear access to a surface on the tube intended to be welded, means for heating (22, 24) the surface, said means being movable relative to the tube-grasping means (16, 18), between a surface-heating position and a withdrawn position, means for heating (26, 28) the mounting bracket (12), and means for grasping (30) the mounting bracket (12), said means being movable relative to the means for heating (26, 28) the mounting bracket (12) and relative to the means for grasping (16, 18) the tube, between a position for heating the mounting bracket (12) and a position for welding the mounting bracket (12) onto the surface of the tube.

The present invention relates to a method of manufacturing a component (1) by additive manufacturing. The method comprises providing a work surface (2) on which the component (1) is to be manufactured, and providing at least one deposition material (3) from which the component (1) is to be composed. The deposition material, typically in the form of wire, is advanced to a localized deposition area (4) where it is added to the component (1) being manufactured. The method further comprises focusing at least one light beam (5) of incoherent light emitted from at least one heating source (6) in the deposition area (4) so that the deposition material (3) is deposited for building up the component (1). At least one light focusing mirror (7) and/or lens (11) is used to focus the incoherent light in the deposition area (4). The invention further relates to the use of such a method in space, such as on a space station, on a space craft or on parabolic flights for testing.

A capacitive discharge (CD) welder includes a charging circuit, a capacitor bank, an insulated gate bipolar transistor (IGBT), a pulse transformer and a secondary circuit. The charging circuit takes incoming electricity and charges a capacitor bank. The capacitor bank stores energy. The IGBT electrically connects and disconnects the capacitor bank to the pulse transformer. The pulse transformer reduces voltage from that stored in the capacitor bank to the desired welding voltage. The secondary circuit electrically connected to the pulse transformer provides a welding current corresponding to the output to the material being welded.

A target and backing plate assembly and method of making the same. The target and backing plate assembly provides a mechanical interlock between the target and backing plate in addition to diffusion bonding between dissimilar materials comprising the target and backing plate. An interlayer may also be used between the target and backing plate. A plurality of ridges, or other salient surface features on one of the target and backing plate are joined to corresponding members or channels on the other of the target and backing plate. The dissimilar materials of the target and backing plate fill negative angled cavities formed by the plurality of ridges and corresponding channels or members of the target and backing plate to accommodate the diffusion bonded dissimilar materials. A target and backing plate assembly with increased strength results.

In accordance with the invention a reactive multilayer foil is fabricated by providing an assembly (stack or multilayer) of reactive layers, inserting the assembly into a jacket, deforming the jacketed assembly to reduce its cross sectional area, flattening the jacketed assembly into a sheet, and then removing the jacket. Advantageously, the assembly is wound into a cylinder before insertion into the jacket, and the jacketed assembly is cooled to a temperature below 100 DEG C during deforming. The resulting multilayer foil is advantageous as a freestanding reactive foil for use in bonding, ignition or propulsion.
