摘　　要：青海华电大通2×300 MW机组工程中主蒸汽管道采用SA335P91钢制造,SA335P91钢在国内属应用推广阶段,该钢种是我省首次在火力发电厂应用的新钢种,本文就具体的现场焊接工艺和技术措施给予了较详细的阐述,对SA335P91钢现场施焊有一定参考意义。The main steam pipe of 2×300MW units of Qinghai Huadian Datong Generating Co., Ltd is made of SA335 - P91 type steel, the new type steel is still in populating phase in domestic, and also it＇s the first time to use this new type steel in Qinghai province. The paper makes a rather detailed expound on its field welding technique and technical measures, and it provides a certain reference for the SA335 - P91 type steel field welding.
