The annealed region of electrical cable conductors which have been butt welded together are restored to their initial work-hardened condition by clamping them on opposite sides of the annealed region and applying forces in either or both the axial and transverse directions to the cables via the clamps so as to swage and work-harden the annealed region. The clamps include means for applying hammer-type forces, including inclined planes for obtaining axially directed forces; and they further include screw thread means for applying gradual swaging forces, as well as screw thread and pneumatic piston means for applying clamping forces.
