前言 在电真空器件和电子元件以及其他一些器件的制作中,金属零件间常用的连接方法以焊接法用得最为普遍。电阻点焊法就是电阻焊接法中的一种最常用的方法。这种方法是将大电流通过二密合母材表面接触点,熔化后,加以压力使之冷却熔合成一体的焊接程序。而焊合处似斑点式样,故称 Introduction In the production of electric vacuum devices and electronic components and other devices, the common connection method between metal parts is most commonly used by welding. Resistance spot welding is one of the most commonly used methods of resistance welding. This method is to pass a large current through the contact surface of the two base metal, after melting, the pressure to make it cool and melt into one welding process. The welding spot like a speckle, so called
