摘要
研究了薄不锈钢内衬20/0Cr18Ni9复合管的焊接工艺和焊接接头性能。通过光学金相、能谱(EDS)成分及线扫描、扫描电镜(SEM)以及力学性能试验等分析方法对焊接接头进行了分析研究,结果表明:采用手弧焊和超低碳CHS 062奥氏体不锈钢焊条焊接20/0Cr18Ni9复合管的过渡层焊缝,能保证复合管使用过程中对焊接接头强度和抗腐蚀性能的要求。
Welding technology and properties of welded joint of 20/0Cr18Ni9 clad pipe with thin stainless steel inner liner were studied. Shielded metal arc welding method with CHS 062 super-low carbon austenitic stainless steel electrode are used to the welding process of 20/0Cr18Ni9 clad pipe. The results show that the welded joint can meet the demands for tensile strength and corrosion-resistance properties in practical service after the investigations on the welded joint by means of optical metaloscopy, EDS line scan, SEM and mechanical property analysis.
