| Abstract: | By summariedly recent researchs on the mechanism of activity's impact on the shape of weld pool and experiental simulation,oxide activity has a significant impact on the shape of weld pool in tungsten inert gas(TIG).And the shape can be improved by covering activity on the surface of base metal.Finally,research methods and the develop trend of welding with activity were concluded. |
