英文摘要	Using environmental welding torch, low current CO2 gas shielded arc welding at flat position was carried out to analyze the change of arc shape, current and voltage, the droplet transfer and weld formation, weld metal tensile mechanics and X-ray radiographic inspection. Fume extraction effect and its influence on welding process and weld quality were evaluated. The results showed that using environmental welding torch is able to dramatically low down the welding fume diffusion to the environment during the low current CO2 gas shielding welding. It will not impact the shape of weld or cause welding defects, although the frequency of droplet transfer of short circuit transition is slightly quickened, the stabilities of suspend droplet and arc get a little worse. The yield strength of weld is slightly decreased, while the tensile strength is slightly increases. © 2019, Editorial Board of Transactions of the China Welding Institution, Magazine Agency Welding.
