在国家标准GB6208-86《钎料牌号表示方法》颁布实施前,国内较为流行的钎料牌号表示方法大体可分为:1.原一机部的钎料牌号表示方法;2.GB340-76《有色金属及合金产品牌号表示方法》;3.其它的表示方法(如各系统内使用的钎料牌号表示方法;新研制应用的钎料直接用主要合金组元的化学元素符号表示法;直接采用国外钎料牌号表示方法)。焊接工作者们应严格执行GB6208-86,使钎料牌号表示方法统一起来。下面将几种常用钎料新旧牌号对比介绍如下。
Before the promulgation and implementation of the national standard GB6208-86 “Brazing material grade indication method”, the more popular domestic solder material grade indication methods can be broadly divided into: 1. The method of expressing the brazing filler metal of the original machine department; 2. The GB340-76 “ Non-ferrous metals and alloy grades that method ”; 3. Other means of expression (such as the brazing filler metal used in the system that the method; the newly developed application of the solder alloy elements directly using the main symbol of the chemical element; direct use Foreign solder grades that method). Welding workers should be strictly enforced GB6208-86, brazing filler metal that unity of means. The following will be several commonly used brazing new and old brands compared as follows.
