Abstract
Disclosed are: a dissimilar material weld joint being formed by joining an iron type material and an aluminum type material and having not only a high strength but also an excellent ductility; and a weld joining method allowing such a joint to be stably produced. A dissimilar material weld jointformed by joining an iron type materialand an aluminum type material, wherein: voidsare formed beforehand on the side of said iron type materialat a predetermined interval along a weld line; both said iron type and aluminum type materials are weld joined so that said voidsare filled with molten aluminum; and the minimum value of the ratio (L-Al)/(L-Fe) of the length (L-Al) of an aluminum type welding materialwith which said voidsare filled to the length (L-Fe) of said iron type materialadjacent to said voidsfilled with said aluminum type welding materialalong said weld lineon the section containing said weld lineis in the range from 0.5 to 7, both the lengths (L-Al) and (L-Fe) being the lengths per 100 mm in length of the weld lineformed after welding.
