摘要： A selective layer melting or other additive layer fabrication method in which powdered material is fused by heating it with a pulsed laser, the pulses being modulated whilst the laser is traversing the substrate so as to control the thickness and/or width of the layer being formed. Initial layers of the fabrication structure may be formed more thickly than subsequent layers, e.g. by means of a CW laser, to reduce distortion. This aspect of the invention may be employed independently of the use of a pulsed laser to form the subsequent layers.

摘要： A method of fabricating an object is disclosed. A first layer of powder is deposited onto a substrate in a configuration defining a first cross-section of the object, and is consolidated by laser irradiation. To fabricate the object, further layers of powder are deposited onto the sintered first layer of powder to define further cross-sections of the object. The further layers are consolidated. A heat source is applied to the substrate to mitigate distortion of the substrate during fabrication of the object.

摘要： A coolant delivery device (100) comprises a coolant outlet (124) and an exhaust (140, 160). The coolant outlet (124) is contained within a housing (150) that has an opening provided with sealing means (180), to which opening the coolant outlet (124) is arranged to direct a coolant. In use of the device, coolant is delivered to a surface to be cooled, and the coolant vaporises at the surface so as to produce coolant gas. Since the sealing means (180), in use of the device, form a seal between the housing (150) and the surface, the coolant gas is constrained to escape the device through the exhaust (140, 160), and does not disturb or disrupt the ambient environment. The device is particularly useful for applying thermal tensioning to welds through the delivery of a cryogenic spray to a weld line.
摘要翻译：冷却剂输送装置（100）包括冷却剂出口（124）和排气（140,160）。冷却剂出口（124）容纳在具有设置有密封装置（180）的开口的壳体（150）内，冷却剂出口（124）的开口被布置成引导冷却剂。在使用该装置时，将冷却剂输送到要冷却的表面，并且冷却剂在表面处蒸发以产生冷却剂气体。由于密封装置（180）在使用该装置时在壳体（150）和表面之间形成密封，所以限制冷却剂气体通过排气（140,160）脱离装置，并且不会干扰或破坏周围环境。该装置特别适用于通过将低温喷雾输送到焊接线来对焊缝施加热张力。
