摘要
分析了耐热不锈钢返修过程中容易出现裂纹的原因,在焊前清理、焊接热输入、层间温度、焊缝成形系数、控制熔合比及锤击去除应力等方面采取措施,避免了焊接裂纹的产生,为耐热不锈钢的焊条电弧焊及其返修积累了实际经验。
The reason of cracks which appears during and/or after heat-resistance stainless steel welding repair was analyzed,the practical experience on heat-resistance stainless steel arc-weld and welding repair was accumulated.The weld crack is avoided by a lot of measures such as pre-weld cleaning,welding heat input,layer temperature,the factors of welding seam form,penetration ratio control,hammer to remove stress.
