| Abstract: | The effect of surface active element on MAG/MIG weldpool fluid flow was studied by means of numerical simulation technology. The active mechanism was revealed that the surface active elements can greatly increase the structure and property of weld metal,and decrease the content of diffuse hydrogen in deposit metal,thus the theory basis was provided to develop new welding material. |
