For example, it is made of stainless steel and has a slightly smaller size, has an opening at the bottom, and the lower edge of the side wall is mounted on the stepped portion of the container l. Therefore, the insides of the container 1 and the cap 2 are in communication with each other. In addition, flanges 6 and 7 facing inward are formed at the boundary between the container l and the cap 2, as necessary, and are connected together with a fastener 8 such as a bolt or nut with a packing 9 sandwiched therebetween. It is considered to be a possible structure.

した溶接用露出部１３か形成されている。On the other hand, the laminated metal plate 5 is made of materials similar to the metal materials of the container I and the cap 2, that is, aluminum and stainless steel, so that the aluminum layer 10 has a thickness of 8 mm and the titanium layer 11 has a thickness of 1+n+n, for example. ,5tJS
It is a composite material made by stacking layers 12 of 8 mm and explosive bonding, and in this case, the aluminum layer 10 is the first welded surface 3.309 of the container l or the welded surface 4 of the cap 2. This corresponds to the material of construction. Furthermore, at the outer edge of the laminated metal plate 5, a part of the aluminum layer 1O is removed along with the titanium layer II and the SUS layer I2 so that the material is of the same type as the constituent material of the surface to be welded 3. A stepped welding exposed portion 13 is formed.

一部をチタン層１１に沿って切削除去するものである。In addition, the laminated metal plates 5 are made by arranging a plurality of sheets in parallel and integrating them by welding, and in the mutual joints 14 caused by the parallel state, the portion that becomes the interface between different metals is removed. The machined hole 15 is drilled so as to. As shown in FIGS. 2 and 3, this processed hole 15 is made by cutting and removing a portion of the titanium layer 11, a portion of the aluminum layer 10, and a portion of the 309 layer 12 along the titanium layer 11. .
そして、加工穴１５の土壁、第１の被溶接面４と接触し

エポキシ系接着剤等からなるものである。Then, as shown in FIG. 3, a welding groove 16 is formed along the earthen wall of the processed hole 15 and the U5 stitches 14 of the 309 layer 12 that are not in contact with the first surface 4 to be welded. In the figure, 17 is an inclined surface, 18 is a sealing material, WA is an aluminum welding metal suitable for welding aluminum layers, and WS is S0.
SUS welding metal suitable for welding 9 layers is shown, the inclined surface 17 is formed gently so as to span the exposed welding part 13 and the processed hole 15, and the sealing material 18 is made of vacuum epoxy adhesive. etc.

実施するものである。And between the first surface to be welded 3 and the exposed part for welding 13,
By performing fillet welding between the second surface 4 to be welded and the 309 layer 12 of the laminated metal plate 5 using appropriate welding materials of the same type, the container l, the gap 2, and the laminated metal plate 5 are integrated with each other. However, for the joint I4 in the metal laminate 14 temporary 5, weld support sealing is carried out as follows.

。That is, the welding groove 16 is welded, and the opening edge of the processed hole 15 intersecting with the seam 14 is welded using the same type of welding material. These welds leave only the inside of the machined hole 15 in a hollow state. Therefore, the sealing material 18 described above is filled into the processed hole 15 up to the edge of the opening and solidified to form a completely sealed structure.

工穴１５の中に充填されたシール材１８とによって密封
構造となる。The dissimilar metal joint connected in this way has the first surface to be welded 3 of the container 1 and the exposed part 1 for welding of the laminated metal plate 5.
3 is welded in a loop shape with aluminum weld metal WA to provide sealing properties, and between the second welded surface 4, which is the surface of the side wall of the cap 2, and the laminated metal plate 5, SU S-based weld metal SOS is welded to provide sealing properties, and the joints 14 in the plurality of laminated metal plates 5 are welded by welding the weld grooves 16 and filling the processed holes 15. A sealed structure is formed by the sealed sealing material 18.
即ち、溶接箇所は、アルミ系溶接金属ＷＡまたはＳＵＳ

って、継手全体の大きさをの制限を受けることがない。In other words, the welding location is aluminum weld metal WA or SUS.
By welding metal materials of the same type, such as weld metal ~ By welding and filling the processed hole 15 with the sealing material 18, the overall size of the joint is not limited.
また、積層金属板５における溶接開先１６の部分の溶接

強度を損なうことを防止できるものである。Furthermore, although the heat capacity of welding the weld groove 16 in the laminated metal plate 5 is small, the processed hole 15 removes the interface between dissimilar metals and forms a hollow part that impedes heat transfer, so there is no thermal effect on the interface. This prevents loss of mechanical strength.
