BRAZING DEVICE AND BRAZING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a brazing device and a brazing method which can well braze dissimilar materials by use of microwave.SOLUTION: A brazing device according to an embodiment comprises: a holding part for holding a structure in which a first member having a first thermal expansibility and a second member having a second thermal expansibility greater than the first thermal expansibility are brought into contact with each other by a brazing material; a microwave generating unit for heating the structure by microwave; a temperature adjustment member which covers the structure; and a controlling unit for controlling the microwave generating unit in such a manner that a first state, in which the first member has a temperature more than that of the second member and the brazing material is melt, is brought into a second state in which the temperature of the first member is reduced at a speed higher than that of the second member and the brazing material is solidified.
