Disclosed is a welding structure including a first member, and a light-transmissive second member. The second member includes a surface having an indented area. The first and second members are welded to each other at closely contacted surfaces thereof by projecting a spot light from the second member side in a state where the second member is in close contact with the first member. A curvature radius of the indented area existing on the surface of the second member, to which the spot light is projected, is at least two times a width of a welding portion.

摘要:
A welding technique closely contacting a light transmissive second member to a first member and radiating deflection-controlled laser light from a second member side to weld both first and second members at a weld interface thereof. A reflectance reducing means is formed by an incident angle adjusting step provided in a cover plate that is disposed on a light radiating surface side of the second member. The reflectance reducing means reduces incident angles of the light at the light radiating surfaces of the first and second members, thus reducing the reflection loss of the laser light at the light radiating surfaces and improving the welding efficiency.
摘要:
A packaging film which shrinks to form at least part of a package when exposed to heat. The packaging film includes a thin film substrate that contracts or shrinks when heated and which is substantially transparent to radiant energy. The film also includes a susceptor material carried by the film that is sufficiently opaque to radiant energy to absorb and transfer to the substrate enough heat energy to cause the substrate to shrink, when the film is exposed to a source of radiant energy. In one embodiment the packaging film takes the form of lids of beverage containers.

摘要:
A vehicle lamp is provided with a lens and a housing. The housing is opened in a front side thereof. The lens is fixed to the housing by laser-beam welding so that the lens covers the front side opening of the housing. The lens is fixed to the housing by bringing the lens, around a full circumference of which laser beam transmitting portions and welding portions are formed, into abutment with the housing, around a full circumference of which a welding portions is formed. The lens is pressed by a press holding jig having a laser beam transmitting portion so as to bring the welding portions of the lens into abutment with the welding portions of the housing. A laser beam is emitted to at least a part of a location where the welding portions of the lens are in abutment with the welding portions of the housing. The laser beam is transmitted through the laser beam transmitting portion of the press holding jig and the laser beam transmitting portion of the lens to at least part of the location. In a segment where the part of the location continues, a sum of a thickness of the laser beam transmitting portion of the press holding jig and a thickness of the laser beam transmitting portion of the lens remains substantially constant in a direction in which the laser beam is scanned.
摘要:
A method and a device for laser joining of plastics or for joining plastics to other materials, which are brought into contact with pressure, with the workpiece closest to the laser beam source being largely transparent for the laser beam, and the second workpiece being as absorbent as possible. By producing a laser beam shaped in the form of a line on the contact surface between the workpieces and by a relative movement of the laser beam relative to the workpieces, designed according to the desired joint seam structure, the workpieces are bonded together accurately only in the desired joining areas. This permits a highly accurate bonding with the smallest possible joint seam distances, so that even parts for micro-systems engineering can also be produced with a short cycle time.

摘要:
The end face of an optical fiber is urged against the highly polished surface of a disk as a laser beam is directed toward the disk to heat the end face above its softening temperature and cause it to conform to the contour and finish of the highly polished surface. A termination ferrule may be simultaneously mounted on the fiber optic cable with a heat bonding agent, using as a heat source either the laser beam or an auxiliary heat source. A hand-held, gun-type unit with a built-in disk and triggered laser can be used to polish and terminate optical fibers in the field.
