Abstract
In order to solve the problem that the concentration of welding smoke exceeds the standard in welding operation, the geometric model of the welding shop was established by ANSYS Workbench, and the RNG k-ε model and the species transport model were used to simulate the diffusion of welding smoke and the distribution law of welding smoke during welding was studied. The results show that the welding dust increases gradually with the action of hot air flow and accumulates at the top of the workshop, and the concentration of welding dust reaches the maximum. It is suggested to set up exhaust facilities on the top of the workshop or blow and suction ventilation system on the top of both sides of the wall to reduce the welding smoke and dust in the workshop and improve the working environment of the welding workshop.
