Arrangement for welding ends of electrical conductor segment pairs of a rotating electrical machine winding

An arrangement for welding the ends of electrically conductive segment pairs, called conductive segments, of a winding of a rotating electrical machine formed by multiple conductive segments mounted in series and supported by a support body (1) so that the ends of each pair of conductive segments to be welded form, on an axial side of the support body (1), a chignon (3) in the form of a slip ring, in which the ends of the pairs of conductive segments to be welded are juxtaposed in a radial direction to the support body and are arranged on the outside of the support body (1) in the form of radial rows (R) that are offset circumferentially from each other;

• said welding arrangement has a flanging tool for the ends of the conductive segments to be welded, and this tool has means for the circumferential locking of these ends to be welded in their welding position, characterized by the fact that the circumferential locking means are formed by cam-shaped sections (19) of flanging members (13, 13′) and by the fact that a cam section (19) is configured so that it is in clamped position between the ends of the two circumferentially adjacent radial rows (R) of conductive segments to be welded by rotating the flanging member.
