| Abstract: | 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. |
