It was found that the solidification cracking susceptibility of weldmetal increases remarkably as nickel content increases.
结果表明:随着焊缝中含镍量的增加,焊缝金属的凝固裂纹敏感性增大。

The improvement of microstructure leads to a considerable reduction of the susceptibility of hot cracking of weldmetal as indicated by the transverse-varestraint test.
增加焊缝中的共晶数量并改善其分布形态,从而有助于降低焊缝金属的热裂纹敏感性。

Disadvantages include risk of hydrogen cracking in carbon steels and weldmetal porosity in aluminium alloys.
