-TIG welding, and more molten metal was blown to the rear by electric arc. As a result, the arc length of A-TIG welding was changed when the tungsten electrode was fixed, and the arc voltage increased... have different effects on welding arc and arc voltage. Due to the fact that SiO2 is a kind of nonmetal oxide whose resistivity is higher than that of metal oxide (e.g. TiO2), the formation of conductive......
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......
Weld Shape Variation and Electrode Oxidation Behavior under Ar-(Ar-CO2) Double Shielded GTA WeldingHidetoshi Fujii,Kiyoshi NogiJoining and welding Research Institute, Osaka University摘 要:Double shielded gas tungsten arc welding (GTAW, also known as tungsten inert gas (TIG) welding) of an SUS304 stainless steel with pure inert argon as the inner layer......
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......
Principles Giving High Penetration under the Double Shielded TIG ProcessDongjie Li,Shanping Lu,Dianzhong Li,Yiyi LiShenyang National Laboratory for Materials Science,Institute of Metal Research,Chinese Academy of Sciences摘 要:A new welding method named double shielded tungsten inert gas(TIG) has been developed to improve the TIG weld penetration.The main......
experiments and recording responses A non-consumable tungsten electrode shielded by inert gas, is used to strike an electric arc with the base metal. The heat generated by the electric arc is used... welding. The preferred welding process of titanium alloy is frequently gas tungsten arc(GTA) welding due to its comparatively easier applicability and better economy. In the case of single pass GTA......
CO2 laser-micro plasma arc hybrid welding for galvanized steel sheets C. H. KIM, Y. N. AHN, J. H. KIM Advance Welding & Joining Research Group, Korea Institute of Industrial Technology.... The boiling temperature of coated zinc is lower than the melting temperature of the base metal, which is steel. In the autogenous laser welding, the zinc vapor generates from the lapped surfaces expels......
