    摘要: A composite griddle plate is provided having a heavy copper core which is diffusion bonded to one or more outer plates of stainless steel, carbon steel or titanium. The copper cored composite is made by explosion bonding the outer metal plates to the copper core to achieve diffusion bonding followed by multi-pass, small, incremental reduction passes in a hot rolling mill conducted within a narrowly controlled temperature range falling within the overlapping hot working range of the copper core and the dissimilar metal of the outer layers.

    摘要: A method of producing an aperture extending from an optically flat surface through a substrate defining the optically flat surface to a surface of the substrate remote from the optically flat surface comprising the steps of: a) forming the optically flat surface; b) etching to form the remote surface to produce an area of the substrate of a desired thinness bounded by the optically flat surface; and c) laser cutting through the area of desired thinness from the remote surface toward the optically flat surface to produce aperture, of a desired shape and size; and a structure when made by the method.

    摘要: A method of welding using a high energy density radiation beam such as an electron beam or preferably a laser beam to weld a pair of sheets using an oblong focused beam spot for reducing the power density of the oblong beam spot to maximize welding speed while minimizing welding defects. The high energy density radiation beam source has a power of at least one kilowatt for achieving Keyhole welding, and a beam delivery system capable of focusing the beam into an oblong spot shape, such as a generally rectangular focused beam spot shape, and directing the beam spot onto at least one of the sheets to weld the sheets. During welding, the beam is focused into an oblong focused beam spot and trained on at least one of the sheets to weld them with the longitudinal axis of the beam spot preferably oriented generally tangent to the weld line, generally parallel to the weld direction, or acutely angled relative to the tangent to the welding direction. Preferably, if a laser is used, it is a laser emitting a continuous wave beam, a pulsed laser operating at a duty cycle of at least 50% such that it substantially performs as a laser emitting a continuous wave beam, or a laser in rippled or modulated mode having a continuous beam component with an average output power of at least 80% of the peak power of the laser so that it substantially performs as a continuous wave laser beam.

    摘要: At least one laser beam is focused on one side of an assembly to be cut at a point on the side which is part of the cutting profile and which is called the point of impact of the beam on side side, in order to cause at that point a disintegration of the material of the assembly. The laser beam is moved in relation to the assembly so that the impact point describes a trajectory which corresponds to the desired cutting profile, while maintaining a controlled atmosphere in the area around the impact point. Uses particularly include cutting solid polymer electrolyte lithium thin film electrochemical generators, or cutting precursors of such generators.
