1. , a kind of welding method that is used for the rotor of electric rotary machine, electric rotary machine comprises an armature core, have groove at its outer circumference portion branch, a rotatable rotary axle that supports armature core, lower floor'"'"'s winding that specified quantity is arranged in one group of groove that is installed on the armature core, with in one group of groove that is installed on the armature core and be positioned over the upper strata winding that specified quantity is arranged of the radial outside of lower floor'"'"'s winding, the step that this welding method comprises has:

  • Lower floor'"'"'s winding and upper strata winding are installed in the groove of armature core;

    Make lower floor'"'"'s winding extension that lower floor'"'"'s winding terminal part branch provides and be installed on upper strata winding extension that the upper strata winding terminal part branch in another groove provides on an outer circumference surface of rotating shaft diametrically one be superimposed on another;

    Die Jia winding extension closely is configured on the circumferencial direction each other in twos;

    WithUtilize a welding torch of an arc welder and utilize the welding torch be in same position on the circumference and interface position at least one situation of doing to radially wobble in the two (is welded in the extension of lower floor'"'"'s winding extension and upper strata winding together at these two winding extensions) at the interface position and welds together.
