ABSTRACT:
A beam welding apparatus for welding a housing and transparent cover of a vehicular lighting device via beam welding has a cover fixing jig having a beam transmitting part, configured to fix a position of a transparent cover and configured to press the transparent cover toward a housing with a welding part of the transparent cover overlaid on a welding part of the housing while it is arranged on the transparent cover. The beam welding apparatus also has a beam irradiating part configured to irradiate beams onto the welding part of the housing through the beam transmitting part and the transparent cover to excite and heat the welding part of the housing. The beam transmitting part has a shielding part configured to shield unnecessary luminous flux among the beams irradiated toward the welding part of the housing from the beam irradiating part.
