Copper is joined to nickel or a nickel containing metal by ultrasonic welding. The method is preferably used to provide connectors for use in multi cell battery systems where the nickel containing metal is required for spot welding to the cell terminals and copper is required to provide the overall conductivity of the connector. In the preferred embodiment, a copper plate 1, provided with holes 2 positioned to correspond to the positive and/or negative terminals of the cells within the battery module, is overlaid with strips of nickel 3, and placed below the anvil 4 of an ultrasonic welding machine for welding. |
