Abstract
Welding fume has the characteristics of small particle size, large damage and difficult to handle. This paper uses the Gambit software and Fluent software to simulate the wind speed, spot spacing and vertical distance factors affecting diffusion welding fume, get the diffusion characteristics of welding fume: in the same section, the greater the spacing, the lower the concentration decreased more quickly; in the same distance, the height of different dust source in the vertical direction, different concentration of welding fumes, smoke concentration is undergoing a process of first increased and then decreased. And put forward, using centrifugal swirl air diffusion, control technology for welding fume entrainment and stratification theory and technology, to achieve effective control of welding fume and energy saving.
