摘要
Abstract
With increasing needs of SAWL pipe, the analysis and research of SAWL pipe performance properties is very important In this paper,the X100 SAWL pipe produced by a foreign steel plant was carried out a series of analysis, including tensile, impact toughness and hardness tests for base metal and welded joint , combined with metallographic analysis, integrated assessment for microstructure and properties of steel was conducted. The results showed that the ensile strength of SAWL pipe welded joints is close to that of base metal, the microhardness of weld metal is higher than that of base metal, and the micro-hardness in HAZ is lower than that of base metal- The submerged arc weld metal is with good toughness, the ductile-brittle transition temperature is-60~-50℃, and the ductile-brittle transition temperature in HAZ is-30~-20 ℃.关键词
