A laser welding structure is provided to decrease a welding cycle time and reduce a processing cost without producing any effect on an external appearance thereof. A laser welding structure welds a first lens(2) to a housing(1) in a combination lamp. A groove(21) is formed on the top of the first lens transmitting a laser so as to concentrate a laser beam, thereby effecting a rapid heat transfer to melt a fusion part(11) fast. A second lens is disposed on the first lens. A protrusion shape corresponding to the groove shape of the first lens is formed on the lower part of the second lens. |
