摘　　要：近年来随着国家大力推广清洁能源的应用使得液化天然气(LNG)接收站工程得以快速发展。LNG储罐的内罐是低温LNG专用存储装置,直接与LNG直接接触,所以LNG储罐内罐的安装焊接质量一直是各方关注的焦点。内罐用9%镍钢的焊条一直为国外进口品牌垄断,因此选用一款性能满足要求的国产焊条作为替代国外进口,解决焊条进口"卡脖子"技术是十分必要的。In recent years,with the vigorous promotion of clean energy,the LNG receiving station project has developed rapidly.The inner tank of LNG storage tank is a special storage device for low-temperature LNG,which is directly in contact with LNG,so the installation and welding quality of the inner tank of LNG storage tank has been the focus of attention of all parties.The welding rod of 9% nickel steel used in the inner tank has been monopolized by foreign imported brands.Therefore,the selection of a performance to meet the requirements of domestic electrode as a substitute for foreign imports,to solve the welding rod import neck technology is very necessary.
