近年来,用摩擦焊接方法焊接的铝铜过渡接头,已经广泛地应用于铝线变压器线圈的引出头及各种引线上.所谓摩擦焊接法,就是根据摩擦生热使金属塑性提高的原理,在一定压力作用下使焊件焊合。摩擦焊接需要在专用的摩擦焊机上进行。焊接过程是铝与铜工件在一
In recent years, the aluminum-copper transition joints welded by the friction welding method have been widely used in the lead-out heads and lead wires of the aluminum transformer coils, and the so-called friction welding method is based on the principle that frictional heat generation increases the metal plasticity. Under certain pressure to weld the weldment. Friction welding needs to be carried out on a dedicated friction welding machine. The welding process is one with aluminum and copper workpieces
