(96 40 416 0 0 ); Microstructure simulation and tribological properties of TIG welding HAZ of ZA12 alloy Abstract: Base on a vast amount of testing and calculations for the welding thermal cycling curves of different testing points in HAZ (heat affected zone) of ZA12 alloy TIG......
aluminum alloy welded joints processed by friction stir welding (FSW) or tungsten inert gas welding (TIG) arc welding was investigated. The effects of welding process and creep stress condition.... In comparison to TIG arc welding,friction stir welding generates better quality joints (with higher yield strength),which possess a fine,homogenous and no pores defect microstructure. Therefore,the FSW......
Visual sensing of weld pool in variable polarity TIG welding of aluminium alloy ZHANG Guang-jun(张广军), YAN Zhi-hong(闫志鸿), WU Lin(吴 林) State Key Laboratory of AWPT, Harbin Institute of Technology...; Abstract: The passive visual sensing method was successfully applied to monitor the weld pool in TIG welding of aluminium alloy......
or oxidizes the coated zinc on the lapped surfaces. Compared with the result from the laser-TIG hybrid welding, the heat input from arc can be reduced by 40%. Key words: galvanized steel; CO2 laser... 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......
. 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 that the arc shape of A-TIG welding used with the SiO2 flux has changed obviously. Key words: welding arc; activating flux; arc shape; arc voltage; stainless steel ......
