摘要
分析SA335-P92钢与焊材的化学成分及力学性能,针对某电厂超超临界机组锅炉主蒸汽管道、再热热段管道的焊接经验,对SA335-P92钢焊前坡口检查控制、管道对口控制、焊前预热控制、现场焊接工艺控制、焊后热处理控制等进行论述,为其它工程SA335-P92钢的焊接提供借鉴。
This paper analyzes chemical composition and mechanical properties of SA335-P92 steel and welding material. Aiming at the weld experience of main steam pipes and reheater pipes of ultra supercritical boiler in some power plant, discusses the edge exam control before welding, pipe counteropening control, preheating control, welding procedure control on-site and control of post-weld heat treatment to take reference for the SA335-P92 steel of other project.
