本文研究了在钎焊过程中,水对母材、钎料、钎剂的影响。并对钎焊中水的来源进行了讨论,对钎剂的配制方法提出了新的看法。为了探求钎焊中水与各工艺参量的关系,继而找出减少或控制水的方法,首次使用了USI-1A数字式微量水分仪,成功的对低真空-氮气分压炉中的水分进行了测定,定量的试验了水对各工艺参数的关系。根据实验所建立的数学模型,提出了在该工艺中水与各参数的计算公式。 This paper studies the effect of water on the parent metal, solder, and flux during brazing. The sources of water in brazing are also discussed. A new view on the preparation of flux is put forward. In order to explore the relationship between water and various process parameters in brazing, and then to find ways to reduce or control water, USI-1A digital micro-moisture meter was firstly used, and the moisture in the low-vacuum nitrogen partial pressure cooker Measurement, quantitative test of the water on the relationship between the various process parameters. According to the mathematical model established in the experiment, the calculation formula of water and each parameter in the process is proposed.
