Abstract

A-TIG welding is a method in which TIG welding is conducted by covering a thin layer of activating flux on the weld bead beforehand.. The emphasis of this paper lies in introducing the development of flux composition, analyzing the influence factors and the mechanism for increased penetration with A-TIG welding of mild steels. Experimental results confirmed that with the developed activating flux of this work, the arc was obviously constricted and the penetration was increased more than two times more than that of current TIG welding for mild steels.
