摘要

奥氏体不锈钢焊缝铁素体含量测定是焊接工艺评定、焊接见证件和焊接材料验收的关键一环

在RCC-M规范中存在模糊和争议之处

据此提出自己的理解和认识

并结合工程实践经验以及焊缝中铁素体的作用和形成机理对焊缝中铁素体含量的测定等一系列问题进行探讨。明确RCC-M中S篇有关奥氏体不锈钢焊缝中δ铁素体含量测定的相关争议项。

Abstract

The measurement of δ ferrite contention in the weld of austenitic stainless steel is a key step of the welding procedure qualification and the acceptance of welding materials and welding certificate. There are controversial and confused points in RCC-M standard about the measurement of δ ferrite contention in the weld of austenitic stainless steel. Put forward some cognition and understanding about the controversial and confused points in RCC-M standard and discuss a series of problems of the measurement of δferrite contention in the weld of austenitic stainless steel combined with the practical engineering experience and formation mechanism of ferrite in weld. The relevant controversial items concerning the determination of δ ferrite content in austenitic stainless steel welds in S section of RCC-M are clarified.
