摘要： 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 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.

摘要： A laser welding method includes positioning two resin molded products that are in contact with each other to a laser head having a mirror, and welding a contact surface of the resin molded products by a laser energy by allowing the laser beam to scan the resin molded products along a welding line with the mirror. The contact surface of the resin products has a first part on which the laser beam is incident at a first angle and a second part on which the laser beam is incident at a second angle larger than the first angle. The welding the contact surface includes controlling a luminous intensity of the laser beam so that the first part and the second part receive a substantially equal quantity of laser energy.

摘要： 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.
