Effect of activating flux on arc shape and arc voltage in tungsten inert gas welding LI Qing-ming(李清明), WANG Xin-hong(王新洪), ZOU Zeng-da(邹增大), WU Jun(吴 军) School of Materials Science.... The experimental results indicate that the SiO2 flux can increase the arc voltage, while TiO2 has no this effect on arc voltage. Compared with conventional tungsten inert gas welding (C-TIG), it is found......
