补充资料:熔焊稀释率
熔焊稀释率
rate of dilution
ronghan xlshlld熔焊稀释率(rate of dilution)金属熔焊或堆焊时,熔教金属被稀释的程度,用母材或预先堆焊层金属在焊缝金属中所占的百分比(即熔合比)来表示。通常,填充金属的成分同母材成分往往并不相同,特别‘是异质金属相焊或合金堆焊时。当堆焊金属的合金成分主要来自填充金属时,局部熔化了的母材在焊缝中的效果可以认为是稀释。因此,熔合比又常称为稀释率。在所有电弧焊焊缝中,都有一定数量的熔化母材和填充金属相混合,只有少数焊缝金属成分与母材成分一样,且因焊缝组织的性质有些独特,所以母材被焊缝过多的稀释而引起成分变化,就会影响焊缝金属的性能,从而影响金属焊接性。 (李维茜)
