PROBLEM TO BE SOLVED: To easily execute brazing and inspection with visual observation by disposing brazing filler metal in a hole of a first member, melting the brazing filler metal under a contacting state of a second member with the brazing filler metal and fixing the first member and the second member with the brazing. SOLUTION: In the hole 90a of the first member 90, the brazing filler metal 110 is laid, and the second member 100 is inserted in the hole 90a so as to interpose the grazing filler metal 110 to allow the second member 100 to contact with the brazing filler metal 110. Successively, the first member 90 and the second member 100 are heated. The brazing filler metal 110 is melted and penetrated into a gap between the first member 90 and the second member 100 and raised into the gap and comes to an outer end of the gap. The second member 100 is naturally dropped, and an end surface of the second member 100 is closely stuck to the bottom surface of the hole 90a. In the hole 90a, a step part is arranged and the brazing filler metal 110 is disposed in the step part. When a pipe material is brazed into the hole of a hollow member, the brazing filler metal 110 is disposed in the hole in the hollow member, the pipe material is brought into contact with the brazing filler metal 110 to melt the brazing filler metal 110. |
