PURPOSE: A laser welder is provided to offer a proper pressing force to an object to be welded, thereby properly forming the gap between panels. CONSTITUTION: A laser welder comprises an optic head unit(20), an elevating unit(40), a roller unit(60), and a pressure sensing unit(80). The optic head unit irradiates a laser to a welded portion of a welded object. The elevating unit is mounted at the tip of a robot arm through the first fixing bracket, is connected with the optic head unit to elevate it. The roller unit is mounted in the optic head unit through the second fixing bracket. The pressure sensing unit is formed at the second fixing bracket correspondingly to the roller unit to sense the repulsive power to the welded object and output the sensed result to the controller. |
