在工厂里,木工和木模工常用带锯来切割木料。这种锯条往往由于操作不惯,而发生折断。为了修复折断了的锯条,过去我们采用气焊和点焊法熔焊。但是,这两种焊接方法要在比较高的温度下进行,因而容易改变金属的原有组织,使带锯的机械性能大大降低,以致丧失了切割材料的基本性能。最近我厂采用银焊料,用钎焊法修复带锯锯条,得到了良好的效果。现在把这种方法介绍如下,供同志们参考。

In factories, carpenters and molders often use band saws to cut wood. This saw blade is often not used because of the operation, and broken. In order to repair the broken saw blade, in the past we used gas welding and spot welding. However, both of these welding methods are carried out at relatively high temperatures, so that the original structure of the metal is easily changed, so that the mechanical performance of the band saw is greatly reduced, so that the basic performance of the cut material is lost. Recently, I use silver solder plant, with soldering method to repair band saw blade, get good results. Now introduce this method as follows, for comrades reference.
