摘要： PROBLEM TO BE SOLVED: To provide a laser brazing method which is suitable for a lap fillet joint of sheet metal.
SOLUTION: The brazing material is melted by irradiation of a laser beam having a wave length of near-infrared light or far-infrared light, while a brazing material made of a copper alloy is being supplied, in a state that a backing material is in contact with an area corresponding to a position whose upper surface side is to be irradiated by the laser beam and the lower surface side is the fillet of the lap fillet joint where a top and a bottom steel sheet members are lapped together. The backing material may be a rotatable member, a slidable member or a close contacting member covering the whole bottom surface of the lap fillet joint, depending upon the position to be applied.
