详情介绍
上海斯米克Z308纯镍铸铁焊条
标准:
符合 GB EZNi-1
相当 AWS ENi-CI
说明:
Z308 是纯镍焊芯,强还原性石墨 型药皮的铸铁焊条,可交直流两用。施焊
时电弧稳定,操作方便,焊件可不预热,其是铸铁冷焊焊条中,抗裂性、切削加
工性、焊缝强度等综合性能较好的一种焊条。
用途:
可用于常温或稍经预热(至 200℃左右)的重要灰口铸铁,如:铸铁薄件的
加工面,汽缸盖、发动机座、齿轮箱以及机床导轨、铸铁制成的机械零件等的焊、
补。
熔敷金属化学成分(%)

≤2.0 ≤2.5 ≤1.0 ≤8.0 ≥90.0 ≤0.03
参考电流:AC 或 DC
焊条直径(mm) 2.5 3.2 4.0 5.0
焊接电流(A) 50~80 80~100 110~140 150~180
注意事项:
1. 首先清除焊接部位的油污、砂、水、锈等污物,并视缺陷类型,开坡口、
打止裂孔及熔池造型等准备措施。
2. 为避免母材熔化过多,减少白口层,施焊中,尽量采用小电流,短弧,窄
道,短道,分散分段焊,每段焊道长度一般不超过 50mm,待温度降至不烫手时
再继续施焊。并且施焊后立即锤击焊缝以松驰应力防止裂纹。
3. 施焊前应将焊条在 150℃左右烘焙一小时。
