PURPOSE:To provide a brazing method in which a bar shape brazing material can be prevented from falling when a metallic conduit/bracket temporary fixing body is delivered in a heating furnace and also, no handling time to set the bar shape brazing material is required and brazing man-hours can be remarkably reduced when the metallic conduit is brazed on the bracket. CONSTITUTION:The metallic conduit 12 is fixed temporarily on the conduit holding part 14a of the bracket 14 by TIG welding or projection welding. and also, the bar shape brazing materials 16 is set on a part predetermined for the brazing of the metallic conduit 12 on the bracket 14. After that, the metallic conduit/bracket temporary fixing body is delivered in the heating furnace, then, the brazing is performed. A brazing material holding hole 18 is formed on the bracket 14 when the press working of the bracket 14 is performed, and also, the bar shape brazing material 16 can be held by force-fitting in the brazing material holding hole 18. |
