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......
Article ID: 1003-6326(2005)05-1081-04 Double-sided gas tungsten arc welding process on TC4 titanium alloy GAO Hong-ming(高洪明), BAI Yan(白 岩), YANG Tian-dong(杨天东) (State Key Laboratory of Advanced Welding Production Technology, Harbin Institute of Technology, Harbin 150001, China) Abstract: TC4 titanium alloy was welded by double-sided gas tungsten arc welding(GTAW) process in comparison......

bonding[4], transient liquid phase bonding[5], gas shielded arc welding[6], laser welding [7-8] have been used to weld these materials. Among the above-mentioned welding technologies, the fusion welding is the most flexible and versatile one. The tungsten inert gas(TIG) and metal inert gas(MIG) arc welding techniques have been employed to weld SiCp/composites[9-12]. However, the high viscosity......

surface can be removed with the leading arc plasma before laser irradiation, so the quality of welding can be guaranteed. Previous studies have primarily used the tungsten inert gas (TIG) arc... input, resulting in an increase in heat input at the lateral sides of the weldment. The plasma arc welding, like TIG welding, utilizes non-consumable electrodes. As the orifice gas and constricting......
