下面介绍几种铝线电机修理时的焊接方法,可供广大农村电机修理者参考。一、铅锌焊它是钎焊的一种。其焊接原理,是将铝、铜加热到低于其熔点温度,填充金属(铅、锌)则加热至熔点温度以上,使它们产生晶间结合,达到焊接的目的。该焊接方法所用设备有:小坩埚一只,专用电炉或其他加热炉一只(如碳炉均可)。焊剂和焊料的配制: 焊剂:松香(粉末)50％,酒精(无水乙醇)50％,在容器里搅拌调匀。焊料:锌95％,铅5％,锌、铅均为粒
The following describes several kinds of aluminum wire welding repair method for the majority of rural motor repair reference. First, lead-zinc welding It is a brazing. The welding principle is to aluminum, copper is heated to below its melting point temperature, filler metal (lead, zinc) is heated to the melting point temperature above, so that they produce intergranular bonding, to achieve the purpose of welding. The welding equipment used are: a small crucible, a dedicated furnace or other heating furnace (such as carbon furnace can be). Flux and solder preparation: flux: Rosin (powder) 50%, alcohol (ethanol) 50%, stirring in the container and mix thoroughly. Solder: 95% zinc, lead 5%, zinc, lead are tablets
