Abstract
A winding on a stator of a rotary electric machine is constructed by welding end portions of a plurality of segments. A plurality of pairs arranged on an end of the stator are welded by a welder. In a welding stage, the pairs are held by a plurality of insertion rods of a circumferential side holding tool. The insertion rods are radially disposed. The insertion rods are movable in a radial direction. The insertion rods are moved back toward a radial outside to release a holding of the pairs after ball-shaped welding marks are formed. Holding is released without damage on the welding mark.
