电力建设科学技术研究所在天津大学焊接教研室的参加与协助之下,于今年5月将铜铝闪光焊接研究成功。这个方法的成功为大量推广以铝代铜创造了有利的条件。解放以来,我国铜的产量虽然有了很大的增长,可是还不能满足工业发展的需要,因此产生了工业用铜不足的问题,所以大力节约用铜及以铝代铜,就成
Under the participation and assistance of the Welding Research Department of Tianjin University, the Institute of Electric Power Construction Science and Technology succeeded in researching the flash welding of copper and aluminum in May this year. The success of this method has created favorable conditions for the extensive promotion of aluminum-based copper. Since the liberation, although the output of copper in our country has greatly increased, it still can not meet the needs of industrial development. As a result, there is a problem of insufficient copper for industrial use. Therefore, great efforts have been made to save copper and substitute copper with aluminum to
