“…Some attempts have been made to the joining of these aluminum sponges just as aluminum sponge in vehicle applications as sandwich part; however, past experimentation on joining or welding of open cell macro-porous sponge has been found in the literature [4,5]. Two late articles have investigated the weld ability and mechanical properties of aluminum sandwich foams of closed cell type [5].…”

Metallic sponges delivered from aluminum 6XXX series are a standout among the most as of late created ultra-lightweight cellular metals. Metallic sponge features exceptionally high-energy ingestion limits with low density and are consequently utilized for boundless applications in the production of ultra-lightweight cellular parts. The manufacture of cellular component parts, for example, hightemperature air or liquid filters and implants, is potential requirement zones relying upon the cell structure size and type of the metal sponge. Metal sponge of closed cell type is ordinarily appropriate for structural uses though open cell sponge; in general, it will be favored for utilitarian applications. Advancement of satisfactory joining innovations for these materials is a basic advance for their far-reaching modern use. The present paper portrays a strong solid-state welding technique that is fit for giving sound joints between aluminum 6XXX macro-porous sponge arrangements. The joining is accomplished by friction stir welding technique abbreviated as FSW through heat generation, softening of material and plastic deformation following the going of non-consumable rotating high-speed steel [HSS] cylindrical tool through the gap between the two solid edges of the sponge to be joined. Having optimized the welding conditions and without utilizing filler metal strong edges were created. The subsequent welds had comparable mechanical properties to that of solid FSW-welded aluminum 6XXX series.

“…For the industrial use of foamed and porous metals as various parts, reliable joining technologies such as welding as well as processing technologies are important. There have been some reports on welding of the conventional porous metals [18][19][20][21][22][23]. However, weldability of porous metals with controlled pore direction such as lotus-type porous metals had not been investigated previously.…”

Lotus-type porous metals, whose pores are aligned in one direction by unidirectional solidification, have a unique combination of properties. These are expected as revolutionary engineering materials with anisotropy of the properties. For the industrial use of the lotus-type porous metals, a reliable joining technology is required. We already reported the melting property of a few lotus-type porous metals by laser welding. These results indicated that these materials possessed anisotropy of melting property with the pore direction perpendicular and parallel to the specimen surface, especially remarkable anisotropy was obtained for the copper specimen owing to the difference of the laser energy absorption to the specimen surface. In this report, the three-dimensional heat transfer analyses, which take into account the difference of the laser energy absorption comparing with the anisotropy of thermal conductivity inherent to lotus-type porous metals, were performed by commercial code with user-defined subroutine. Predicted profile of weld fusion zone is in good agreement with the cross-sectional view obtained by experiments.

Lotus-type porous metals, whose pores are aligned in one direction by unidirectional solidification, have a unique combination of properties. These are expected as innovative engineering materials with anisotropy of the properties. A reliable joining technology such as welding is required for the industrial application of the lotus-type porous metals as well as processing technology. We have already investigated the melting property of the lotus-type porous copper and magnesium by laser beam irradiation and have pointed out that these materials possessed anisotropy of melting property with the pore direction perpendicular and parallel to the specimen surface, especially remarkable anisotropy was obtained for the lotus-type porous copper owing to the difference of the laser energy absorption to the specimen surface. In this study, three-dimensional finite element calculations of temperature distribution for the lotus-type porous copper as well as the lotus-type porous magnesium under the non-steady-state conditions were performed in order to investigate the effect of the anisotropy of the laser energy absorption comparing with the anisotropy of thermal conductivity inherent to lotus type porous metals. The effect of these factors on the profile of fusion zone by comparing the results of numerical simulation and the experimental observations were discussed.
