自从我们在《湖北机械》1981年第一期上报道了有关铸铁水冷焊法的消息以来,省内外有关单位来信索取有关资料以及了解该项工艺的操作等事项。为此,我们在原有基础上,又进行了一定的工艺试验以及实地考查,对水冷焊法焊接工艺的某些理论问题进行了探讨。同时,通过试验归纳出这种工艺进行的原则和施焊时的注意事项。 Since we reported on the first phase of “Hubei Machinery” in 1981 about the water-cooled welding of cast iron, we have received letters from relevant agencies both inside and outside of China and obtained information on the operation of the process. To this end, we based on the original, but also carried out a number of technical tests and field tests on the water-cooled welding process some of the theoretical issues were discussed. At the same time, the principle of this kind of process and the precautions during welding are summarized through experiments.
