  • Patent number: 10421153
    Abstract: In a laser welding method, first, laser light is irradiated on one side surface of one of the metal members to form a protruding portion projecting from the other side surface on the opposite side. Next, a part of the protruding portion that was formed is melted by scanning the laser light to generate a metal melt flow toward a top of the protruding portion so as to form a protrusion. The protrusion projects farther from the other side surface than a height of the protruding portion that was initially formed. Then, the one of the metal member having the protrusion is superposed on another of the metal members so that the protrusion is interposed therebetween. Next, the laser light is irradiated onto a portion where the metal members are superposed to weld the metal members to each other.

  • Patent number: 10071444
    Abstract: A laser cladding apparatus includes a powder supplier to supply metal powder to a portion to be processed, a laser to irradiate the portion to be processed with laser so as to melt the metal powder for cladding, and a controller. The powder supplier includes a gas pressure gauge, and the controller stores, as an initial value, a gas pressure value measured by the gas pressure gauge when the metal powder supplied by the gas pressure reaches the portion to be cladding-processed. In operation after storing the initial value, the controller sets, as a reference time, timing when the gas pressure gauge measures a same pressure as the initial value, and outputs a start signal for laser irradiation to the laser based on the reference time.

  • Patent number: 10059624
    Abstract: The present disclosure relates to a system for repairing a damage site on a surface of an optical material. The system may have an Infrared (IR) laser which generates a laser beam having a predetermined wavelength, with a predetermined beam power, and such that the laser beam is focused to a predetermined full width (“F/W”) 1/e2 diameter spot on the damage site. The IR laser may be controlled to maintain the focused IR laser beam on the damage site for a predetermined exposure period corresponding to a predetermined acceptable level of downstream intensification. The laser beam may heat the damage site to a predetermined peak temperature which causes melting and reflowing of material at the damage site to create a mitigated site.

  • Patent number: 10005153
    Abstract: Provided is a laser beam welding apparatus capable of correctly detecting the beginning and the end of one welding point even in remote laser beam welding. The laser beam welding apparatus includes a head which irradiates a workpiece with a laser beam, an optical receiver which receives a reflected light of the laser beam from the workpiece, and a controller. The optical receiver receives only a laser beam and a plasma of the reflected light. The controller determines that one welding point begins when a time during which intensity of the reflected light is larger than or equal to a second set-intensity is longer than or equal to a first set-time, and determines that the one welding point ends when a time during which the intensity of the reflected light is smaller than or equal to a first set-intensity is longer than or equal to a second set-time.

    Abstract: A stent and method for treating an end of a pre-woven stent is provided. The method includes providing a pre-woven stent including a plurality of sharp ends. A pair of wire portions that extend in opposite helical directions around the stent are bent and woven into the stent to define a pair of overlapping crown portions. When the wires are woven into the stent a double weave portion of the stent is defined. The wires can be cut to define tail portions that are removed from the stent, leaving a single crown portion. The sharp ends can be alternatively treated by curving the ends to define rounded looped ends.

  • Patent number: 9969000
    Abstract: A method of fabricating a joining preform includes the step of printing a self-fluxing joining alloy. Joining includes brazing and soldering. The self-fluxing joining alloy contains at least one of phosphorus, boron, fluorine, chlorine, or potassium. Another printing step prints a non-phosphorous joining alloy. Both printing steps are performed by an additive manufacturing or 3D printing process. The printing a self-fluxing joining alloy step may be repeated until the non-phosphorous joining alloy is substantially encapsulated by the self-fluxing joining alloy. The self-fluxing joining alloy may be a BCuP alloy, a CuP alloy, a CuSnP alloy, a CuSnNiP alloy or a CuAgP alloy. The non-phosphorous joining alloy may be a BAg alloy, a BNi alloy or a BAu alloy.

  • Patent number: 9956646
    Abstract: Multiple-beam laser processing may be performed on a workpiece using at least first and second laser beams with different characteristics (e.g., wavelengths and/or pulse durations). In some applications, an assist laser beam is directed at a target location on or within the workpiece to modify a property of the non-absorptive material. A process laser beam is directed at the target location and is coupled into absorption centers formed in the non-absorptive material to complete processing of the non-absorptive material. Multiple-beam laser processing may be used, for example, to drill holes in a substrate made of alumina or other transparent ceramics. In other applications, multiple-beam laser processing may be used in melting applications such as micro-welding, soldering, and forming laser fired contacts. In these applications, the assist laser beam may be used to modify a property of the material or to change the geometry of the parts.
