WELDING METHOD, WELDING DEVICE, AND BATTERY MANUFACTURING METHOD |
摘要 |
A welding process (S1), which uses a welding device (1) that welds a welding object using a pulse laser, wherein a first light-receiving unit (20) receives only infrared rays having a wavelength that allows detection of the keyhole formed in the molten pool from among the infrared rays emitted from the welded portion of the welding object during welding and an analysis unit (40) assesses the quality of the welded portion on the basis of the intensity of the infrared rays received by the first light-receiving unit (20). |
