Abstract

The welding torch with an exhaust hood can effectively capture welding fumes at the source of contamination. However, due to the high temperature of the welding fumes, the temperature of the welding torch handle is relatively high in a short time and the resistance of the ventilation handle is also too high, which makes it difficult to apply in practice. In order to reduce the resistance of the ventilation handle, and promote the smooth outflow of high-temperature welding fumes, the pressure loss of the three welding torch handle structures was studied in this paper by simulation. The structure models of the welding torch handle were established by Auto CAD, and the air distribution and resistance in the ventilation handle were simulated by Fluent. According to the simulation results, the influence of the different structures and air volumes on the resistance of the ventilation handle was analyzed. The result shows that the ventilation handle B of the welding torch has the least resistance and the resistance of the ventilation handles increases rapidly with the increase of air volume.
