Z408焊条/斯米克Z408焊条/Z408铸铁焊条

上海斯米克Z408镍铁铸铁焊条 
 标准: 
符合GB EZNiFe-1 
相当AWS ENiFe-C1 
 说明: 
Z408是镍铁合金焊芯,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,其焊缝金属的特点是颜色与母材最接近,强度高,
塑性好,线膨胀系数低,抗裂性对灰口铸铁与Z308差不多,但对球墨铸铁则比
Z308强,对含磷量较高(0.2%P )的铸铁,也有良好的效果。焊缝金属比Z308
和Z508稍硬。 
 用途: 
可用于常温或稍经预热(至200℃左右)的灰口铸铁及球墨铸铁的焊、补。
如汽缸、发动机座、齿轮等。 
 熔敷金属化学成分(%) 
C Si Mn Ni Fe S 
≤2.0 ≤2.50 ≤1.80 45.0~60.0 余量 ≤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. 为避免焊条药皮发红及母材熔化过多,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。
