Abstract
A method for manufacturing a structure in which an edge portion of the structure formed by stacking a plurality of members is friction stir welded. The manufacturing method includes: a welding step of forming a friction stir welded portion by bringing a friction stir welding tool from a side of a surface of a member on one side into contact with a superposition portion of works in which the members are stacked while rotating the friction stir welding tool; and a cutting step of cutting the friction stir welded portion, and in each of two or more works produced by the cutting, a welded portion of the edge portion of the structure is formed with the cut friction stir welded portion.
Claims13
A method for manufacturing a structure in which an edge portion of the structure formed by stacking a plurality of members is friction stir welded, the manufacturing method comprising:
- a preparing step of preparing a predetermined number of works, each of the works having unwelded edge portions and having stacked layers of the members by stacking the members;
- an arranging step of arranging the works flatly such that the unwelded edge portions of the works are placed in contact with each other to be flush;
- a welding step of forming a friction stir welded portion by bringing a friction stir welding tool from a surface of one of the stacked members on one side into contact with a superposition portion of the works in which the members are stacked while rotating the friction stir welding tool;
- and
- a cutting step of cutting the friction stir welded portion to divide the arranged works into the predetermined number of works,
- whereby in each of the works obtained by the cutting, a junction portion of the edge portion of the structure is formed with the cut friction stir welded portion.
A method for manufacturing a plurality of works each having a container member, a lid member and a component member, the manufacturing method comprising:
- a stacking step of stacking the component member within the container member and the lid member on the container member to form each of the works;
- an arranging step of arranging the works flatly such that the unwelded edge portions of the works are placed in contact with each other to be flush;
- a welding step of forming a friction stir welded portion by bringing a friction stir welding tool from a surface of the lid member into contact with a superposition portion where the lid member is stacked on container member while rotating the friction stir welding tool;
- and
- a cutting step of cutting the friction stir welded portion to form individually cut works.
A method for manufacturing a plurality of works each having a first member and a second member, the manufacturing method comprising:
- a preparing step of preparing a predetermined number of works having original sizes, each of the works having unwelded edge portions and having stacked layers that comprises the first member and the second member by stacking the same;
- an arranging step of arranging the works flatly such that the unwelded edge portions of the works are placed in contact with each other to be flush;
- a welding step of forming a friction stir welded portion by bringing a friction stir welding tool into contact with a superposition portion where the second member is stacked on the first member while rotating the friction stir welding tool;
- and
- a cutting step of cutting the friction stir welded portion to form individually cut works,
- whereby the cut works obtained by the cutting are respectively provided with the original sizes in the preparing step.
