本文简要介绍焊接残余应力对应力腐蚀开裂的影响,重点叙述低碳钢硫化物应力腐蚀开裂的室内试验及焊后回火的作用,最后介绍生产中降低焊接残余应力的常用方法。
This article briefly introduces the influence of welding residual stress on stress corrosion cracking. It mainly focuses on the laboratory tests and post-weld tempering of low-carbon steel sulfide stress corrosion cracking. Finally, the common methods of reducing welding residual stress in production are introduced.
