第一机械工业部于七月三十日对各专业局和省市工业厅局发出“关于在锻模中大力推广堆焊先进工艺的通知”。通知首先说明:四、五以来,有些工厂试验用铸钢模体、堆焊型槽的方法(简称铸造堆焊锻模)制造锻模,来代替锻造合金钢锻模,在2、4、5吨各种型锻锤上,取得良好效果。今年第一汽车厂与清华大学合作,试验用自动堆焊方法制造大型锻模,结果良好,现在顺利地继续使用。
The first Ministry of Machinery Industry on July 30 issued to all professional bureaus and provincial industrial bureau, “on the die forging vigorously promote the welding of advanced technology notice.” Notice First of all: Since the fourth and fifth, some factories have experimented with cast steel mold body, surfacing groove method (referred to as casting surfacing forging die) forging die, instead of forging alloy steel forging die, in 2,4,5 Tons of various forging hammer, and achieved good results. This year the first automobile factory and Tsinghua University, experiment with automatic welding method of manufacturing large forging die, the result is good, and now continue smoothly.
