本文研究了铝真空钎焊过程中零件经化学清洗后的存放方式、保存方法和保存时间等工艺因素对钎焊质量的影响。试验表明,无论是以零件或组合件的形式存放,也无论是保存在塑料袋内或纱布包好放在产品箱内,皆可长时间贮放而不影响钎缝质量。此结论为真空钎焊铝波导的批生产创造了必要条件。本文对此研究结果进一步从钎焊过程的机理方面进行了分析和探讨。 This paper studies the vacuum brazing parts of aluminum parts after chemical cleaning storage, preservation methods and storage time and other process factors on the quality of brazing. Tests show that whether stored in the form of parts or assemblies, whether stored in plastic bags or wrapped in gauze, the product can be stored for a long time without affecting the quality of the solder joints. This conclusion creates the necessary conditions for the batch production of vacuum brazed aluminum waveguides. In this paper, the research results are further analyzed from the aspect of brazing process.
