在过去几年中,我厂曾经生产和试制了三种类(?)低碳钢焊条,即氧化钛型、高锰型及碳酸气型配方。下面就是我厂在制造和试制中所得到的一些经验和意见。 42号灰色焊条——氧化钛型配方上海各电焊条制造厂所生产的氧化钛型配方很多,其中比较完善的一个配方是由韋文林工程师与铁道部共同协作研究成功的,我们称之为42号灰色焊条。这种焊
In the past few years, our factory has produced and trial-produced three types of (?) Mild steel electrodes, namely titanium oxide type, high manganese type and carbonated gas type. Here is my factory in the manufacture and trial of some of the experience gained and opinions. No. 42 gray electrode - titanium oxide formula Shanghai welding electrode manufacturer of titanium dioxide produced by many formulations, including a relatively complete formula by Wei Wenlin engineers and the Ministry of Railways to work together to study success, we call it No. 42 Gray welding rod. This kind of welding
