参考词条
补充资料：焊接:冷压焊
在常温下只靠外加压力使金属產生强烈塑性变形而形成接头的焊接方法。加压变形时﹐工件接触面的氧化膜被破坏并被挤出﹐能净化焊接接头。所加压力一般要高於材料的屈服强度﹐以產生60～90％的变形量。加压方式可以缓慢挤压﹑滚压或加衝击力﹐也可以分几次加压达到所需的变形量。冷压焊的工件一般是塑性金属﹐如铝﹑铜﹑鎘﹑镍和银等。冷压焊有搭接点焊和对接焊两种。搭接点焊前工件表面须经机械加工﹐或用钢丝刷(轮)或溶剂仔细清理﹐对接焊时表面清理要求不太严格。冷压焊设备只需一台挤压机﹐包括压膜和夹持钳口﹐也可用手动夹具焊接小工件。冷压焊时工件不必加热﹐因而适於焊接不允许有温昇的工件和加热时会引起软化的材料﹐也适用於易產生脆性化合物的异种金属连接。冷压焊已应用於电容器外壳的封装﹑电气工业中铝铜过渡接头﹑导电母线﹑引出线﹑铝製日用品和包装带的焊接等。铝与铝对接可焊截面达1500毫米2 ﹐铝与铜对接可焊截面达1000毫米2 。冷压焊所需设备简单﹐工艺简便﹐劳动条件好。但冷压焊所需挤压力较大﹐在大截面工件的焊接时设备较庞大﹐搭接焊后工件表面有较深的压坑﹐因而在一定程度上限制了它的应用范围。
