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球的裂纹——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。
Abstract As welding is conducted for the steel with quanched tendency using electrode Cr30Ni10 as bottem runs and LZ60 as deposition metal, a special cracking—fustion zone cracking can be found in weld metal of different steel weld joint. The conditions of occurrence and effected facors for this kind of cracking are studied in the paper. The optimun low hydrogen process that can prevent weld metal from cracking is put forward, too.
