Abstract: A laser welding method includes: a first step of irradiating a target with a first laser beam; and a second step of irradiating a melting region melted in the first step with a second laser beam to maintain a melting amount of the melting region. The first laser beam is irradiated in a first configuration in which an output of the first laser beam is lowered by a predetermined amount when a predetermined time elapses, and an output of the second laser beam is set to be smaller than the output of the first laser beam, or in a second configuration in which the first laser beam includes a laser beam having a first wavelength and a first output, and the second laser beam includes a laser beam having the first wavelength and an output smaller than the first output, and/or being in a defocused state.

Abstract: A removing apparatus (2) includes a first removing section (11) and a second removing section (12). The first removing section (11) includes a rotating disk (15) and a driven roller (16). The rotating disk (15) has a pair of left and right first to fourth left and right removing blades (21) to (24) attached thereto. When the rotating disk (15) rotates in a counterclockwise direction, a coil conductive wire (3) sandwiched between the rotating disk (15) and the driven roller (16) is transferred in a transfer direction. When the rotating disk (15) rotates in a counterclockwise direction, the left and right side surface portions of the insulating coating (4) are removed by a blade portion (21b) of a pair of left and right first left and right removing blades (21).

Abstract: A stripping apparatus and a stripping station capable of reducing cycle time for steps of stripping an insulation coating from a conducting wire material are provided. A stripping apparatus configured to strip an insulation coating WL from a conducting wire material W, including the insulation coating WL and cross-section of which orthogonal to a longitudinal direction has a rectangular shape, the stripping apparatus includes: an upper mold 150 provided with a stripping blade configured to strip the insulation coating WL; a lower mold 110 configured to support the conducting wire material W from a lower side thereof; a pressing member 130 configured to prevent displacement of the conducting wire material W; and a rotation mechanism configured to rotate the conducting wire material W around a rotational axis C1 that is parallel to a axial center of the conducting wire material W.

Abstract: A peeling apparatus 1 includes a first peeling die and a second peeling die respectively including a pair of cutting blades 251 that peels the insulating film by being moved in a direction perpendicular to an axial direction of the conductive wire material 2 to cut the insulating film, and a support die 253 that supports a side surface of the conductive wire material 2 from a downstream side in a moving direction of the cutting blades 251 at the time of cutting by the cutting blades 251, the support die 253 of the first peeling die including a convex portion 2533 protruding toward the conductive wire material 2.
