Abstract
In a friction agitation joining method for joining two plate-shaped joining members butted against each other with a level difference formed at upper surface sides thereof by a joining tool having a probe rotatable about a rotation axis thereof, the butted joining members are arranged so as to be inclined to a horizontal plane with one of the joining members having a higher upper surface level positioned at a lower side and the other at a higher side. Then, the rotating probe is inserted into a butted portion of the joining members or the vicinity thereof in a state that the rotation axis is parallel to a vertical plane extending along the butted portion. Then, the probe is moved relative to the joining members along the butted portion with the probe inserted into the butted portion or the vicinity thereof.
Claims11
A friction agitation joining method for joining two plate-shaped joining members butted against each other with a level difference formed at upper surface sides thereof by utilizing a joining tool having a probe rotatable about a rotation axis thereof, said friction agitation method, comprising the steps of:
- inclining said butted joining members with respect to a horizontal plane so that one of said joining members having a higher upper surface level is positioned at a lower side and the other of said joining members having a lower upper surface level is positioned at a higher side;
- inserting said probe rotating about said rotation axis into a butted position of said butted joining members or the vicinity thereof in a state that said rotation axis is generally parallel to a vertical plane extending along said butted portion;
- and
- moving said probe relative to said butted joining members along said butted portion with said probe inserted into said butted portion or the vicinity thereof.
