PROBLEM TO BE SOLVED: To provide a heating brazing device using hydrogen gas in which the hydrogen gas is used as a burning source and stable brazing is easily carried out. SOLUTION: A gap between gas leading out pipes 3 is adjusted and set by elastically deforming both gas leading out pipes 3 adjusted to a size of an object 15 to be brazed and a gas injection direction of a gas injection port 8 of both fire nozzle bodies 8 is set. After this setting, a mixture gas of the hydrogen gas is introduced to a gas leading pipe 1 and ignites the mixture gas injected from the gas injection port 7. Thereby, burning flame is produced such that it surrounds an approximately whole of the brazing position of the object 15 to be brazed. COPYRIGHT: (C)2004,JPO
