    • Welding between a rotor and shaft is accomplished by first placing the shaft within a movable holder of a pressure device. The rotor is then placed in the lower or stationary holder of the pressure device. Each holder is an electrode that can electrify the shaft and rotor. The stationary holder is a cup or container which has inside the cup, a low melting point alloy which conducts electricity from the lower electrode to the rotor to prevent concentration of electricity. Welding is finished by lowering the shaft onto the rotor which is in the cup which is heated to liquefy the low melting point alloy. As the shaft and rotor are pressed together, current is passed through each by the electrodes. The junction of the shaft and rotor are melted and thus joined. After cooling, any of the low melting point metal which remains on the rotor is removed by inserting the rotor in boiling water.
    • 通过首先将轴放置在压力装置的可移动保持器内来实现转子和轴之间的焊接。 然后将转子放置在压力装置的下部或固定的保持器中。 每个支架是可以使轴和转子通电的电极。 固定保持器是在杯内部具有低熔点合金的杯子或容器,其将电力从下电极传导到转子以防止电力集中。 通过将轴降低到被加热以液化低熔点合金的杯中的转子上来完成焊接。 当轴和转子被压在一起时,电流通过电极通过。 轴和转子的接头熔化并因此结合。 在冷却之后,通过将转子插入沸水中来除去保留在转子上的任何低熔点金属。
