| Abstract: | In this paper the law in the effects of current frequency,size of tungsten pole and composition of shielding gas on the arc stability in low-current TIG welding is revealed by a large number of experimental results.It comes to a concIusion that when the welding current is 6-8A,high-pulsed welding will hold the arc stabilty on condition that the current is over 20KH_2,the sheilying gas is mixed with Ar+2%H_2,and the diameter of Se tungsten pole is less than 0.5mm. |
