COLD PRESSURE WELDING OF COPPER TROLLEY WIRES

The optimum method for cold welding of copper trolley wires was experimentally determined, then the mechanical properties and the aging characteristic of the welded joint as well as the influence of impurities in copper on cold weldability were investigated. The practical device was developed from the results. Since 1970, many cold welded joints have been included for tests, as a step to wider application, in copper trolley wires on lines in the suburbs of Tokyo.
