本発明は、２個の発泡金属部材の接合方法に関
するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for joining two foamed metal members.

製造されている。Conventional technology Foamed metal members have countless air bubbles dispersed inside them, and have a low specific gravity of 1.0 g/cm 3 or less (for example, a foamed aluminum plate has a specific gravity of 0.2 to 0.3), and is lightweight, fireproof, and noncombustible. It has excellent heat resistance (foamed aluminum plate has thermal conductivity of 0.45Kcal/m.hr.℃) and sound absorption. This foamed metal member has conventionally been manufactured by adding a foaming agent to molten metal in a mold, stirring, leaving to foam, and cooling and solidifying.

る。Problems to be Solved by the Invention Foamed metal members are manufactured by the above method, but currently only 300 mm
When foaming products up to the size of 600 mm x 300 mm (thickness) and even larger products, a large mold is used to carry out the specified processing, resulting in a large cavity near the center of the foam. As a result, various performances are extremely low and it cannot be used in practice. Therefore, if large foam metal parts are required, the only option is to join members of the size described above, but since they are made up of countless bubbles, welding is impossible, and joining with ordinary adhesives is not possible. However, there are problems in that the adhesive easily deteriorates over time and is flammable. These points are one of the reasons why foamed metal members are not used in a wide range of applications, even though they have various excellent properties as described above.
本発明は、上記のごとき問題点が全く認められ
ない、発泡金属部材の新規な接合方法を提供しよ
うとするものである。 The present invention aims to provide a novel method for joining foamed metal members, which is completely free from the above-mentioned problems.

て強固に接合される。Function As described above, by pouring molten metal into the groove where the end surfaces of the two foam metal members to be joined are butted together, and cooling and solidifying the molten metal, each foam metal member The end surface to be joined contacts and melts the molten metal, and the molten metal enters into the air bubbles present in the end surface to be joined,
When the molten metal is cooled and solidified, the metal layer and each end face to be joined are firmly joined by fusion and anchor effect, and as a result, the two foamed metal members are firmly joined via the metal layer.

Beveling was performed on the end surfaces 1a and 2a of each short side of the 100 mm thick sheet, and the two were butted together to form a bevel portion 3 with a bevel angle of 90°. A patch plate 4 is placed on both sides of the groove 3.
a and 4b and preheated at 250°C, molten aluminum 5 heated to 900°C was poured into the groove 3 and filled. After the molten aluminum 5 was left to cool and solidify, the backing plates 4a and 4b were removed, and it was found that both the foamed aluminum plates 1 and 2 were firmly joined via the aluminum layer. On the side surfaces of the joint, the contact surfaces of the foamed aluminum 1 and 2 with the molten aluminum 5 are melted and fused to the aluminum layer after solidification. )
A solid state was observed in which the bubbles 1b and 2b present were penetrated into the bubbles 1b and 2b.
