| Abstract: | A TIG welding as a high efficient welding procedure is developed and a serial experiment on bead welding is conducted by using it. The results show that under the same welding conditions, welding arc is remarkably constricted, the penetration is remarkably increased, and the width of weld is reduced a little after covering the welded surface with activating flux. The emphasis of this paper lies in introducing the development of flux composition, analyzing its influence on the penetration, and preliminarily analyzing the mechanism of penetration increment. |

| Keywords: | A-TIG welding weld penetration activating flux arc constriction surface tension |
