ロウ付け方法は、上記構成により、下記のような理由に
より、ロウ付け工数が全体として大幅削減可能となる。According to the brazing method of the metal pipe and the bracket of the present invention, the man-hour for brazing can be greatly reduced as a whole for the following reasons due to the above-mentioned configuration.
【００２２】ロウ材をロウ材保持孔に圧入するため、
ロウ材のセット位置が安定し、ロウタレのおそれがない
とともに、ロウ付け不良が発生するおそれがない。In order to press the brazing material into the brazing material holding hole,
The brazing material setting position is stable, there is no risk of sagging, and there is no risk of defective brazing.
【００２３】上記と同様の理由で、加熱炉に搬入す

加熱炉への搬入姿勢も制限されず、搬入後、ロウ材を治
具等を使用して整列させる必要もない。For the same reason as described above, there is no fear that the rod-shaped brazing material will drop when it is carried into the heating furnace. For this reason,
The carrying-in attitude to the heating furnace is not limited, and it is not necessary to align the brazing material with a jig or the like after the carrying-in.
【００２４】ロウ付け保持孔の形成及びロウ材のセッ
