摘要
石油化工领域用焊接接头往往需要具有较好的力学性能和耐腐蚀性能。对于设计较为复杂及环境较为特殊的结构件,一般焊接技术的效率低且焊接质量较难保证,药芯焊丝焊接技术在这方面具有优势。文中综述了双相钢药芯焊丝焊接的特点,尤其是药芯焊丝焊接在水下焊接和获得良好的焊接接头性能等应用方面进行了介绍,并对其在石油化工领域应用的前景进行了阐述。
The welded joints in petrochemical industry often need to have good mechanical properties and corrosion resistance.For the structural parts with complicated design and used in special environment,the welding efficiency of general welding technology is low and the welding quality is difficult to guarantee,while the flux cored wire welding technology has advantages in this respect.The characteristics of dual phase steel flux-cored wire welding were summarized,especially the application of flux-cored wire welding in underwater welding and obtaining good welded joint performance were introduced, and the prospect of its application in petrochemical industry was described.
