A manufacturing method for a liquid flow-path member including a flow path between a first substrate and a second substrate layered together, the method including a welding step for welding the first substrate and the second substrate together, in which in the method, the first substrate is formed of a material that blocks ultraviolet light and absorbs laser light, the second substrate is formed of a material that blocks ultraviolet light and transmits laser light, and in which the welding step includes melting, with laser light passing through the second member, a joint surface where the first member and the second member are joined to weld the first member and the second member together.

A vehicle lamp includes a lamp housing having an inner space and a welding surface, and a cover that covers the inner space and is joined to the lamp housing by laser welding to be disposed adjacent to another vehicle lamp. The cover includes a design surface portion and a welding leg. An end portion of the outer peripheral portion of the design surface portion on another vehicle lamp side is provided as an adjacent side end portion. The welding leg includes a facing surface portion that protrudes from the adjacent side end portion and faces the other vehicle lamp. The facing surface portion is provided at a position extending from an upper end portion to a lower end portion of the adjacent side end portion.

There is provided a resin molded product including a first member and a second member which are laser welded. A laser welded portion includes a first welding portion which is welded by laser welding of galvano method and a second welding portion which is welded by laser welding of flash method or laser welding of scanning method.

An outer lens for a lighting fixture for a vehicle includes a first region formed of a first material and a second region formed of a second material adjacent to the first region. The first material transmits light in a visible light range. The second material has a first wavelength range with transmittance equal to or less than a first transmittance. A second wavelength range has a transmittance equal to or more than a second light transmittance. A third wavelength range is between the first wavelength range and the second wavelength range. The first wavelength range includes a visible light at an S wavelength or a shorter wavelength. The second wavelength range includes a wavelength range from an M wavelength to an L wavelength. The third wavelength range increases from the S wavelength to the M wavelength. The first wavelength range includes the emission wavelength.

A laser welding method and system for joining portions of first and second workpieces of thermoplastic material that is partially permeable to a laser beam but absorbs radiation from the laser beam. The first and second workpieces, which are made of material that absorbs radiation from a laser beam, are clamped together. A mask is placed on a first surface of the first workpiece, the first surface being opposite the surface engaging the second workpiece. The mask is impermeable to a laser beam and forms a slot for passing a laser beam to the portion of the first surface of the upper workpiece exposed by the slot, so that heating and melting of the material of the workpieces is limited to the width of the slot. A laser beam is directed onto the slot and moved in a manner to illuminate the slot to melt and join the workpieces.

Method for joining a fluid conduit and a connection hub. There is provided a method for joining a fluid conduit 2 and a connection hub 7, wherein a fluid 2 conduit is provided having an at least partially transparent end section 1. Also provided is a connection hub 7 comprising a hub cavity 9 having a shape complementary to a shape of the end section of the fluid conduit 1. The end section of the fluid conduit 1 is at least partly introduced into the hub cavity 9 through an opening in the hub, wherein a contact interface between at least a lateral wall part of the end section 1 and a hub cavity 9 wall is established. The method includes heating a target zone 27 in the contact interface, for joining the fluid conduit 2 and the connection hub 7 at the target zone 27, by directing a light beam 29 across the at least partially transparent end section 1 of the fluid conduit 2 from a side of the fluid conduit 2 which is opposite a side of the target zone 27.

A vehicle lamp includes a lamp housing having an inner space and a welding surface, and a cover disposed adjacent to another vehicle lamp, and configured to cover the inner space and join to the lamp housing by laser welding. The cover includes a design surface in which an outer surface of an outer peripheral portion is formed as a curved surface and a welding leg that protrudes from a portion near the outer peripheral portion in the design surface. An annular portion on an inner peripheral side of the curved surface on an outer surface of the design surface is formed as a laser light incident surface. The curved surface is positioned on an outer peripheral side from an intersection point of a virtual line and the outer surface of the design.
