我厂焊工小组长刘子如同志,在技术员张静涛同志的帮助下,积极贯澈苏联专家的建议获得很大的成绩。他根据苏联专家的建议,用冷焊铸铁法来补救铸件上的缺憾,使大批铸件免於报废,因而为国家节约了大量的资金。现在我们把这种方法介绍如下,供同志们参考。冷焊铸铁法用的焊条有两种,一种是蒙内耳合金焊条,一种是普通的铜钢焊条。 With the help of our technician Comrade Zhang Jingtao, Liu Zi-ru, the team leader of our welder, has made great achievements in actively adhering to the suggestion of Soviet experts. Based on the suggestion of the Soviet experts, he used the cold welding cast iron method to remedy the shortcomings in the castings so as to save a large number of castings from being scrapped, thereby saving the country a large amount of money. Now let’s introduce this method below for your reference. There are two kinds of electrode for cold welding cast iron, one is Monel alloy electrode and the other is ordinary copper electrode.
