A joining method is disclosed wherein a mechanical contact between a first metal member (1A, 1C, 1E, 101A, 101C, 101E, 111A, 101G, 111C, 111D) and a second metal member (1B, 1D, 1F, 101 B, 101 D, 101 F, 111B, 101 H, 110) is established. At least the first metal member (1 A, 1C, 1 E, 101 A, 101C, 101 E, 111A, 101 G, 111C, 111D) or at least the second metal member (1B, 1D, 1F, 101 B, 101 D, 101 F, 111 B, 101 H, 110) exhibits a surface with various heights. Then a welding process by friction stirring with a stirring pin (F2) of a rotation tool (F) is performed, wherein, of the rotation tool (F), only the stirring pin (F2) contacts with any of the first metal member (1A, 1C, 1 E, 101 A, 101C, 101 E, 111 A, 101 G, 111C, 111D) and the second metal member (1B, 1D, 1F, 101 B, 101 D, 101 F, 111 B, 101 H, 110). The welding process may be configured to insert the stirring pin (F2) of the rotation tool (F) such that an insertion depth of the stirring pin (F2) is kept approximately constant. |
