CRIMPED TERMINAL AND PRODUCTION METHOD AND PRODUCTION DEVICE FOR CRIMPED TERMINALS

摘要

Provided are a method and an apparatus for manufacturing a crimp terminal capable of achieving a good state of conduction between the conductor portion of a coated wire and a crimp terminal. A laser welding device (3) is provided with a laser machining head (61), and carries out welding of a butted interface (Td) of a pre-welding crimp terminal (Tb) from the laser machining head (61). An output power density and a sweep rate of the laser light irradiated from the laser machining head (61) are adjusted so that sputter (S) which is ejected from a weld portion (W) of a butted interface (Td) of the pre-welding crimp terminal (Tb) adheres to an inner surface of the pre-welding crimp terminal (Tb).
