摘　　要：自保护药芯焊丝焊缝金属中氧、氮含量较高 ,而塑性、韧性较低。根据自保护焊接化学冶金原理 ,分析了铝、钛等金属对脱氧和固氮的作用 。The content of oxygen and nitrogen is higher in the weld seam of self-shielded flux cored wire and the descent of weld seam metal plasticity and toughness. According to the chemical metallurgy principle of self-shielded weld and the analysis on the deoxidization and nitrogen fixation of the metal such as aluminium, titanium,and etc.this paper analyzes the proper chemical composition for self-shielded weld.
