钎焊是连接金属和合金的有效方法之一,特别是在精密仪表制造工艺方面,它占有相当重要的地位,目前常以钎焊来代替熔焊。 过去我厂采用焊枪加热来焊接电流电压表的分流器接头(图1),不但生产率低,质量难保证,而且成本高,劳动条件差。因此,现在改为电接触钎焊。 Brazing is one of the most effective methods for joining metals and alloys. It plays a very important role especially in the manufacture of precision instruments. At present, brazing is often used instead of welding. In the past I used welding torch heater to weld current and voltage meter shunt connector (Figure 1), not only low productivity, quality is difficult to guarantee, and the high cost, poor working conditions. Therefore, it is now changed to electrical contact brazing.
