Abstract:
A method of joining transformer winding conductor cables is disclosed. The ends of the conductor cables to be joined are first chamfered to both clean and taper the respective ends. The tapered ends are then overlapped and pressed together. Vibratory energy is then applied to at least one of the overlapped ends to weld the cleaned conductor cable ends together to form a joint that has substantially the same cross sectional area as the conductor cables themselves.
