Abstract:
To provide an aluminum joined body capable of improving welding quality by preventing solidification cracks.SOLUTION: An aluminum joined body includes a first member 1 which is an aluminum wrought and a second member 2 which is an aluminum die-cast material, and has a welding part 10 where the first member 1 and the second member 2 have been welded together. A welding bead 12 of the welding part 10 includes at least one factor component that can cause a solidification crack. The concentration of the factor component in the welding bead 12 falls out of a peak concentration value of crack sensitivity, and the concentration of the factor component in the welding bead 12 of the welding part 10 is higher than the concentration of the factor component in the first member 1.SELECTED DRAWING: Figure 1
