摘要
Abstract
In this article, it adopted high temperature and high pressure reaction kettle and electrochemical technology to research CO2 corrosion behavior of steel pipe welded joints under two kinds of welding process (GTAW and GTAW+SMAW). The results indicated that the corrosion rate of welded joints with GTAW+SMAW welding process is lower than that of GTAW welding process; the corrosion rate of two kinds of welding process decreases with corrosion time increasing,the surface of corrosion product film becomes density;the cross section of corrosion product film becomes thicker and more closely. The main composition of corrosion products are (Fe, Ca) CO3 compound salt and Fe3O4.关键词
