摘要
Cr30Ni10型+LZ60焊条焊接易淬火钢时,在异种钢焊缝金属中发现了一种特殊的裂纹———熔合区裂纹。本文研究了这种裂纹的生成条件及其影响因素,提出了有效防止裂纹发生的低氢优化工艺。
As welding is conducted for the steel with quanched tendency using electr ode Cr30Ni10as bottem runs and LZ60as deposition metal,a special cracking-fusion zone cracking can be found in weld metal of different steel weld joint.The conditions of occurrence and effected factors for this kind of cracki ng are studied in the paper.The optimum low hydrogen process that can preven t weld metal from cracking is put forward,too.
