铝—铜焊接问题,国内许多兄弟厂矿、学校和研究单位已总结出一些好的方法。结合我厂生产情况,我们采用了闪光焊的方法,即在普通对焊机上稍加改进,使其既能焊钢料,又能焊接铝—铜接头。改装目的电机常用的铝导线和铜导线一般都是近于纯铝和纯铜。它们的特征是导电性好、导热性高,在接近焊接温度时有脆性,并且只能在很窄温度范围内具有焊接时所需的塑性。因此,在一般接触焊机上进行焊接是比较困难的,必须采用带“快速顶锻装置”的焊机来进
Aluminum - copper welding problems, many domestic factories and mines, schools and research institutes have concluded some good ways. Combined with the production of our factory, we adopted the method of flash welding, that is, ordinary butt welder slightly improved so that it can both weld steel, but also welded aluminum - copper joints. Refit purpose motor commonly used aluminum wire and copper wire are generally close to pure aluminum and copper. They are characterized by good electrical conductivity, high thermal conductivity, brittleness near the soldering temperature, and plasticity required for soldering only in a very narrow temperature range. Therefore, the general contact welding machine welding is more difficult, must be used with “quick forging device” to enter the welder
