Development and application of activating fluxes in TIG welding

摘要：

The developing and application of activating flux which can dramatically increase the depth of weld bead penetration and improve the properties of weld bead using fusion welding process was summarized. The mechanisms of the activating flux increasing the depth of weld bead penetration especially the theories of arc constriction and the change of temperature gradient of surface tension were analyzed. The research work indicates that the activating flux will be used in more welding process to obtain deep weld penetration, high productivity, low deformation and excellent joint mechanical properties.
