For this purpose, a fitting part 3 is provided in a part of the joining part of the copper block 2 to the stainless steel pipe l, a brazing margin 4 is provided in the remaining part, and a brazing material 5 is poured into the gap between the copper block 2 and the stainless pipe 1. I was wearing it.

Moreover, there remained a gap, poor airtightness, and insufficient concentricity.

なる。(Function) As described above, in the method of joining a stainless steel vibrator and a copper block of the present invention, the brazed portion of the stainless steel vibrator is plated with copper, so the copper plated portion has good wettability and is easy to braze on the fitted copper block. The brazing filler metal smoothly enters the gap between the two parts and creates a brazed joint between copper and copper, resulting in a stable brazing strength with high brazing strength and little variation.

でろう付けした。First, to explain one example, kJ shown in FIG.
<A masking 6 was provided on the outer periphery of a stainless steel vibrator 1 with a diameter of 4.2 mm and a wall thickness of 0.2 mm, except for a predetermined portion to be copper plated, and a copper plating 7 was applied over a length of 10 mm.
After that, after applying flux to the copper plating 7, it was made to have a diameter of 10 mm and a length of 9 mm as shown in FIG.
A copper block 2 with a mating part 3 of 5 mm, inner diameter 4.25 m+I+, and length 3.5+ nm and a brazing allowance 4 of 4.5 mm inner diameter and 6 ml length 11 is fitted, and a brazing material is applied to the fitted part. As low melting point solder (Pb5%-Δg15%-
1n) 5 was heated with a burner (not shown) and poured into it for brazing.
次に従来例について説明すると、第３図に示す如く上記

ろう付けした。Next, to explain a conventional example, as shown in Fig. 3, the same stainless steel vibrator 1 as in the above embodiment is not plated with copper, but the same copper block 2 as in the embodiment is fitted at a predetermined position on the outer periphery of the stainless steel vibrator 1. Then, low melting point solder (P b 5%-A g 15%-I
n) No. 5 was heated with a burner (not shown) and poured in for brazing.

のであった。When we inspected the cross-sections of the brazed parts of the 10 products of the example and the conventional example that were brazed in this way, we found that the solder metal did not wrap around the conventional product and could not be joined, but the product of the example had no brazing material. The brazing material went around sufficiently, filling the gap at the brazing allowance 4, and was completely joined, resulting in a stable brazing strength with high brazing strength and little variation.
しかもろう付け部分には隙間が無いので、気密性が高く
、ステンレスバイブ１と銅ブロック２との同芯度が高い
ものであった。Moreover, since there was no gap in the brazed portion, the airtightness was high, and the concentricity between the stainless steel vibrator 1 and the copper block 2 was high.

As a result, brazing strength is high and stable with little variation.
