Method for manufacturing laminated core and laminated core

Abstract

A method for manufacturing a laminated core is provided that makes positions of boundary parts of laminated blocks and improves an efficiency of a welding operation of the blocks. The above-described object is achieved by the method of manufacturing the laminated core 10 including a process that forms a plurality of blocks 12 having a plurality of welding parts 13 to 15 of different forms or colors at intervals of prescribed angles in the circumferential direction, a process that laminates the plurality of blocks 12 under a state that the blocks are rotated at intervals of the prescribed angles and a process that welds the welding parts 13 to 15 having the different forms or colors of the laminated blocks 12 to form integrally the plurality of blocks 12.
