テンレスとの接合方法を要旨とするものである。 Therefore, the inventors of the present invention have conducted intensive research on the groove for butt joints, weld build-up shape, and brazed type weld joints when joining dissimilar materials between aluminum alloy members and stainless steel, which are highly desired. As a result, we have completed the present invention. That is, in forming a dissimilar joint between an aluminum alloy member and stainless steel, the present invention provides at least a final thin layer of silver plating on the stainless steel side, and connects the stainless steel and aluminum alloy member having the thin silver plating layer to the aluminum alloy member. Welded with alloy welding parts,
The gist of the present invention is a method of joining aluminum and stainless steel, which is characterized by providing extra thickness and an overlapping part so that stress transmission between the stainless steel and the weld metal can be achieved in a shear type manner.

1000℃程度と考えられる。 In Fig. 1, 1 is a stainless steel member and 2 is an aluminum alloy member. When butt-welding the two, a step is provided on the stainless steel member 1 as shown in the figure, and the ends of the aluminum alloy member 2 are overlapped. A spigot type bevel is used. At this time, the stainless steel member 1 is subjected to appropriate pre-processing such as sandblasting as necessary, then copper or nickel plating is applied to improve adhesion, and finally silver plating 3 (20μ to 50μ) is applied. Rub. Make a wide bevel on the aluminum alloy member 2 side and attach it here.
Weld metal 4 is heaped up by TiG welding using 43S (aluminum alloy containing 5% Si) as a filler metal. This weld metal 4 blends well with the silver-plated surface 3 of the stainless steel and joins with it while melting a part of it. The base material of stainless steel does not melt at all. By the way, the melting point of 43S is approximately
600℃, the melting point of silver is 960℃, and the melting point of stainless steel is approx.
The temperature is 1500℃. The temperature at which molten metal flows toward the silver plating layer during TIG welding is
It is thought to be around 1000℃.

ロー式の開先をとつているものである。 This method is not welding in the original sense because it is not fused with the base metal, but it looks like
A welded butt joint is created. However, since this is not welding, the strength must be handled as shear stress in zones A and B, which are the overlapped parts, rather than in zone C in FIG. Therefore, an extra thickness d and an overlap part A are provided. In particular, since zone A and zone B are separated by C, it is important to use this as an arm to withstand the moment. Otherwise, the stainless steel and aluminum alloy will peel off from the boundary due to the bending moment. There is a risk. Therefore, a zone B is provided on the stainless steel side in the front and a spigot type bevel is created.

If the load is not known, it is necessary to consider the strength of the base material, the plate thickness, etc., and select a to be quite long.
