Abstract

A tailored blank material 10 is configured by welding a plurality of steel plates 12, 14, and 16. At least one steel plate 12 among the plurality of steel plates 12, 14 and 16 is welded to other steel plates 14 and 16 so that the rolling direction 12a thereof differs from the rolling directions 14a and 16a of the other steel plates 14 and 16. Thickness of at least one steel plate among the plurality of steel plates 12, 14, and 16 may differ from thickness of other steel plates.

Claims

1. A tailored blank material which is configured by welding a plurality of rolling members, wherein

at least one rolling member among the plurality of rolling members is welded with another rolling member so that the rolling direction of the rolling member is different from the rolling direction of the other rolling member.

2. The tailored blank material according to claim 1, wherein

thickness of at least one rolling member among the plurality of rolling members is different from thickness of another rolling member.

3. The tailored blank material according to claim 1, wherein

material of at least one rolling member among the plurality of rolling members is different from material of another rolling member.

5. The tailored blank material according to claim 2, wherein

material of at least one rolling member among the plurality of rolling members is different from material of another rolling member.

4. A method of manufacturing a structural member using a tailored blank material which is configured by welding a plurality of rolling members, comprising the steps of:

preparing a tailored blank material which is welded so that a rolling direction of at least one rolling member among the plurality of rolling members is different from a rolling direction of another rolling member; and

forming the tailored blank material so that a deformation amount in the rolling direction is to be larger than a deformation amount in a direction crossing the rolling direction for each of the plurality of rolling members.
