用铝导线代替铜导线不但能节约大量纯铜,而且还能大大降低导电系统的重量。但是到目前为止,铝导线特别是多股铝导线的封端焊接问题,解决得还不够完善。要使多股铝导线的封端既能保证质量,又能符合大量生产的要求,目前还没有见到完整的资料。例如我厂生产的桥式超重机上的铜导线要将它全部改为铝导线,在一个月内就有成千上万的封端过程。以目前几种适用于铜铝焊接的先进工艺来看,如摩擦焊接、铜铝导线的热压
Using aluminum wire instead of copper wire can not only save a lot of pure copper, but also greatly reduce the weight of the conductive system. But so far, aluminum wire, especially multi-strand aluminum wire end-sealing welding problem, the solution is still not perfect. In order to ensure the quality of multi-strand aluminum wire end caps, but also meet the requirements of mass production, so far have not seen the complete information. For example, the copper wire on the bridge overweight machine in our factory should be changed to aluminum wire, and there are tens of thousands of capping processes in a month. To the current several suitable for copper and aluminum welding advanced technology point of view, such as friction welding, copper and aluminum wire hot pressing
