PROBLEM TO BE SOLVED: To provide a brazing device and a brazing method capable of excellently brazing.SOLUTION: A brazing device 1 brazes a first joining object member 210 and a second joining object member 220, and comprises two or more of preheating laser devices for preheating a joining object part P by emitting a preheating laser, a brazing material sending-out device for sending out a brazing material 110 toward the preheated joining object part P in the rear of the preheating laser devices in the brazing direction and a melting laser device for melting the brazing material 110 by irradiating the brazing material 110 sent out by the brazing material sending-out device with the melting laser. When the melting laser device emits the melting laser, a shadow S of the brazing material 110 is formed in the joining object part P, and the preheating laser emitted by the two or more of preheating laser devices overlaps in front of the shadow S. |
