自行车的焊接量虽然不大,但也是自行车制造中的一种主要工艺。例如,自行车架是用钎焊方法连接的,它是车架质量好坏的关键。以前自行车的钎焊是用焦炭炉进行的,这种方法不仅生产率低,而且质量很差,成本又高。我们参考苏联的经验,经过无数次的试验,成功的将盐浴炉硬钎焊工艺应用到生产上。实践证明,此种方法是合乎多快好省的原则的。盐浴炉钎焊的过程,是将已装好的零件或部件,在其接头旁边或接头内部装上焊料(图1),然后将零件 Although the amount of bicycle welding is not large, but it is also a major process in the manufacture of bicycles. For example, bicycle frame is connected by brazing method, it is the key to the quality of the frame. In the past, brazing of bicycles was carried out using a coke oven. This method not only had low productivity, but also poor quality and high cost. We refer to the Soviet Union’s experience, after numerous tests, the successful application of salt bath furnace brazing process to production. Practice has proved that this method is in line with the principle of much faster and better. Salt bath furnace brazing process is to have the installed parts or components, in the connector next to or within the connector with solder (Figure 1), and then the parts
