一、钨触头简单介绍钨触头是飞机、坦克、汽车、拖拉机以及仪器仪表的电器部件所用的点接触元件。一般尺寸很小,是普通碳素钢单件同钨片利用钎焊联接起来的。图1所示焊件是电器部分所用钨触头结构的一种。二、真空钎焊为了使钨片同普通碳素钢单件通过钎料牢固地钎焊在一起,必须在整个钎焊过程中严格防止制件产生氧化。目前普遍采用的是气体保护钎焊法,即在钎焊时通 First, a brief description of tungsten contacts Tungsten contacts are aircraft, tanks, cars, tractors and instrumentation electrical components used in the point of contact components. The general size is small, ordinary carbon steel with a piece of tungsten brazing together. The weld shown in Figure 1 is a type of tungsten contact used in the electrical part. Second, the vacuum brazing In order to make common with single-piece carbon steel tungsten brazing solid brazing together, the brazing process must be strictly in the oxidation of the workpiece. Currently widely used is gas brazing method, that is, when brazing pass
