METHOD FOR MANUFACTURING LAMINATED CORE, LAMINATED CORE, AND WELDING MACHINE |
| 摘要 |
A method for manufacturing a laminated core includes a laminating process of obtaining a laminate in which a plurality of core pieces are laminated, and a welding process of forming a weld bead which extends in a thickness direction of the laminate on a side surface of the laminate. In the welding process, a heat input when a center portion in a longitudinal direction of the weld bead is formed is greater than a heat input when an end portion of the weld bead is formed. |
