| Abstract: | Using water cooled copper testing device,coupled with series of agglomerate fluxes made by the present laboratory,welding experiments have been conducted to extract the rapid cooled droplets in submerged arc welding.With the help of LECO oxygen-nitrogen analytical instrument,the oxygen and nitrogen contents in droplets have been measured,and scan electron microscope has been applied to explore internal morphology or analyze micro-zone chemical composition so as to discuss mechanism of oxygen gaining occurring in droplet reaction zone. |

| Keywords: | submerged arc welding droplet reaction zone oxygen gaining mechanism |
