制冷机管接头自动火焰钎焊机的研制

国内许多制冷设备厂在铜合金管接头焊接一般都采用手工火焰钎焊工艺，其质量稳定性较低、生产率不高，为了改变这一状况，我们在了解和吸收国外同类产品的优点和可用之处的基础上，结合生产实际情况，研制开发了自动转盘式、氧－液化石油气混合火焰钎焊设备，代替手工操作，使生产的产量、质量的稳定性都有了明显的提高，设备也能满足长期工作的生产要求。

Development of Automatic Flame Brazing Machines For Tube Tie-in of Refrigerators

Many manufacturers of refrigerators in China employ the technique of manual flame brazing in tube tie - in welding. Such a technique can easily lead to low stability in quality and low production. To change the situation, we develop a flame brazing machine by combining the merits of foreign congener automatic brazing machines with our production. This machine can improve both the yield and quality stability; at the same time it can satisfy the needs of long-term production.
