Dissimilar material weld joint formed by joining iron type material and aluminium type material, and weld joining method |
摘要 |
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 joint 1 formed by joining an iron type material 2 and an aluminum type material 3, wherein: voids 4a are formed beforehand on the side of said iron type material 2 at a predetermined interval along a weld line 6; both said iron type and aluminum type materials are weld joined so that said voids 4a are filled with molten aluminum 7; and the minimum value of the ratio (L-A1)/(L-Fe) of the length (L-Al) of an aluminum type welding material 10 with which said voids 4a are filled to the length (L-Fe) of said iron type material 2 adjacent to said voids 4a filled with said aluminum type welding material 10 along said weld line 6 on the section containing said weld line 6 is 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 line 6 formed after welding. |
