我厂在焊补灰口鉄铸件缺陷时,因为蒙内耳合金焊条买不到,曾用普通软钢焊条来修补,焊补后硬度太高无法进行机械加工,在过渡区域还有1～2公厘的白口。后改用铜钢焊条和铸鈇焊条也解决不了过渡区域的白口问题。后来根据本刊1957年7期所介绍的材料进行了多次试验,并做了一些改进,使焊补中遇到的问题得以解决。现在把我们取得的初步经验介绍出来和各兄弟厂交流。
I plant welding gray 鉄 鉄 castings defects, because the Inner Mongolia alloy welding rod can not be bought, had to use ordinary mild steel electrode repair, welding hardness is too high to be machined in the transition area there are 1 to 2 public PCT white mouth. After the switch to the use of copper steel and cast iron electrode can not solve the problem of white area in the transition area. Later, according to the publication of the magazine in 1957 7 introduced a number of tests carried out and made some improvements so that the problems encountered in welding repair can be resolved. Now let us introduce the initial experience and communicate with the brothers plant.
