我厂生产中,经常要用钎焊的方法钎焊一些特殊结构的另件,或用来修补结构复杂的散热器。我们遵照毛主席关于“人类总得不断地总结经验,有所发现,有所发明,有所创造,有所前进”的伟大教导,结合我厂的实际情况,自制了汽油钎焊设备。这种设备和钎焊材料各厂都可以制造,钎焊工艺也很简单,易于推广。若用氧—乙炔焰钎焊,由于火焰的温度太高,再加火焰与熔剂的相互作用,使钎焊过程很难进行。而用这种汽油空气焊枪可以得到柔和的火焰,与铝基钎 I plant production, often with brazing method to braze some of the special structure of the other pieces, or to repair the complex structure of the radiator. In accordance with Chairman Mao’s great teaching on “mankind always summarizes experiences, discoveries, inventions, innovations and advances”, we have made a self-made gasoline brazing equipment based on the actual situation in our factory. This equipment and brazing materials can be made at various plants, brazing process is also very simple and easy to promote. If oxygen - acetylene flame brazing, the flame temperature is too high, coupled with the interaction between the flame and flux, the brazing process is difficult. And with this gasoline air gun can get a soft flame, and aluminum brazing
