Porous aluminum is a multifunctional metal material with a light weight and high energy absorption. In our previous study, it was shown that press forming during the foaming of a precursor can form porous aluminum while maintaining its porous structure. In this study, the jointing of porous aluminum by press forming during the foaming of multiple precursors was investigated. The precursors were fabricated via the friction stir welding route. The jointing and shaping of porous aluminum were simultaneously carried out by press forming of the precursors with maintaining their porous structures. From a four-point bending test of the obtained samples, the joint strength was found to be equivalent to the strength of the base porous aluminum. No oxide films were observed at the fracture surfaces generated at the surface of the precursors, which prevented jointing between multiple porous aluminum while porous structures were obtained, which indicated good jointing.
