BEAM OF LIGHT PROJECTION DEVICE AND WELDING EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a beam of light projection device and welding equipment which enable the cost thereof to be reduced, and enable the surroundings of welding places to be easily visualized.

SOLUTION: The beam of light projection device for irradiation with a beam of light introduced by a bundle of optical fibers obtained by bundling a plurality of optical fibers, is characterized in that the bundle of optical fibers is divided into a plurality of portions at beam exit parts 3a and each of the plurality of the beam exit parts 3a has a beam condensation optical system and causes outgoing beams via the beam condensation optical system to cross each other.
