厚壁SA-765 Gr3低温钢容器埋弧焊焊接技术的研究

摘要

By a series of experiment and study, the submerged arc welding technology which is used for thick-wall low temperature steel vessel by adopting the domestic welding material has been prepared, so as to greatly increase the production efficiency.By means of application and verification, the property of whole welded joint can meet the operating requirement at low temperature.%通过一系列试验研究,制定出一套采用国产焊材应用到厚壁低温钢容器焊接制造的埋弧焊技术,极大地提高了生产效率.经产品应用验证,整个焊接接头性能满足低温使用要求.
