Abstract
Systems and methods are provided for fixturing hairpins for joining by welding. A fixture system includes an outer structural ring fixed relative to an inner structural ring and mates with the component around its hairpin type conductor ends. Dielectric rings are disposed between conductor pairs. Clamp rings are disposed on opposite sides of the dielectric rings. One clamp ring and one dielectric ring define an opening receiving one conductor pair. Another clamp ring and another dielectric ring define another receiving another conductor pair. The clamp rings are movable toward one another to align and crowd the conductor pairs between the clamp rings and the dielectric rings prior to welding.
