    摘要: Provided is a laser welded body which can be manufactured without undergoing complicated steps and maintain the characteristics of a resin contained in a resin member, which exhibits high welding strength even when scanned with a laser beam at a high speed, and which can be manufactured at high production efficiency.
    The laser welded body 10 comprises a first resin member 1 which is a laser-irradiated subject which contains a thermoplastic resin and nigrosine sulfate and has an absorbance a1 of 0.09 to 0.9; and a second resin member 2 which contains a thermoplastic resin as the same kind as or different kind from the thermoplastic resin and a laser beam absorbent, and has an absorbance a2 of 3.0 to 15, wherein the first resin member 1 and the second resin member 2 are laser-welded at a part at which the both resin members are overlapped and/or butted.

    摘要: An optical cable and method for forming an optical cable is provided. The cable includes a cable jacket including an inner surface defining a channel and an outer surface. The cable includes a seam within the cable jacket that couples together opposing longitudinal edges of a wrapped thermoplastic sheet which forms the cable jacket and maintains the cable jacket in the wrapped configuration around the plurality of optical fibers. The method includes forming an outer cable jacket by wrapping a sheet of thermoplastic material around a plurality of optical core elements. The method includes laser welding together portions of thermoplastic material of opposing longitudinal edges of the wrapped sheet such that a seam is formed holding the sheet of thermoplastic material in the wrapped configuration around the core elements.

    摘要: A system and method for laser sealing an edge portion of a covering of an architecture-structure covering is disclosed. In one embodiment, after cutting a covering of an architectural-structure covering to an appropriate size, lasering the cut edge portions or surfaces of the covering to seal the cut edge portions or surfaces of the covering to prevent fraying. The beam of the laser may be positioned to contact the cut edge portions or surfaces of the covering in a plane of the fabric. Subsequently, the beam of the laser scans or moves across the surface of the cut edge portion of the covering. In use, the beam of the laser is arranged and configured to apply heat to the surface of the fabric material at discrete points or spots to vaporize any loose fibers located along the cut edge portion of the covering.

    摘要: Provided is a laser welded body which can be integrated through a laser-welding step without undergoing complicated steps even through use of the same or difference resin members each other, which has excellent welding strength between the resin members, which maintains the characteristics of a resin contained in the resin member and which exhibits the high welding strength by improving meltability of the resin members yet under a laser-welding condition of a medium and high scan speed.
    A laser welded body comprises a resin member(s) which contains a thermoplastic resin and nigrosine sulfate having a sulfate ion concentration of 0.3 to 5.0% by mass and has an absorbance a of 0.09 to 0.9, an adjoined part where the resin member(s) is overlapped and/or butted, and at least a part of the adjoined part is laser-welded.
