Abstract
Official abstract text for this publication.
A production method of rotary electric machines is provided that can laser weld the leading end parts of a plurality of electrical conductors projecting from respective slots with high joint strength. A production method of rotary electric machines that produces a rotary electric machine by joining, by way of laser welding, leading end parts of a plurality of electrical conductors inserted in respective slots provided in a stator core and projecting from the respective slots, includes the steps of matching and arranging the leading end parts of two adjacent electrical conductors; and joining the leading end parts of the two adjacent electrical conductors by irradiating a laser onto the two adjacent electrical conductors from a direction sloped at an angle relative to a joining face of the leading end parts of the two adjacent electrical conductors.

What is claimed is: 1. A production method of rotary electric machines that produces a rotary electric machine by joining, by way of laser welding, leading end parts of a plurality of electrical conductors inserted in respective slots provided in a stator core and projecting from the respective slots, the method comprising the steps of: matching and arranging leading end parts of two adjacent electrical conductors; and joining the leading end parts of the two adjacent electrical conductors by irradiating a laser onto the two adjacent electrical conductors from a direction sloped relative to a joining face of the leading end parts of the two adjacent electrical conductors, wherein two members being composed of the same material and having the same width in a direction orthogonal to the joining face are used as the two adjacent electrical conductors, wherein a laser irradiation angle in relation to the joining face is set at 5 to 15° in the step of joining, wherein the leading end parts of the two adjacent electrical conductors are arranged so as to have different heights in the step of matching and arranging, and wherein the laser is irradiated from a side of the electrical conductor having a lower height of the leading end part in the step of joining. 2. A production method of rotary electric machines that produces a rotary electric machine by joining, by way of laser welding, leading end parts of a plurality of electrical conductors inserted in respective slots provided in a stator core and projecting from the respective slots, the method comprising the steps of: matching and arranging leading end parts of two adjacent electrical conductors; and joining the leading end parts of the two adjacent electrical conductors by irradiating a laser onto the two adjacent electrical conductors from a direction sloped relative to a joining face of the leading end parts of the two adjacent electrical conductors, wherein two members being composed of the same material and having the same width in a direction orthogonal to the joining face are used as the two adjacent electrical conductors, wherein a laser irradiation angle in relation to the joining face is set at 5 to 15° in the step of joining, wherein an irradiation position of the laser is set to between the leading end parts of the two adjacent electrical conductors in the step of joining, wherein the leading end parts of the two adjacent electrical conductors are arranged so as to have different heights in the step of matching and arranging, and wherein the laser is irradiated from a side of the electrical conductor having a lower height of the leading end part in the step of joining.
