Abstract

There are various methods for welding fume control. These methods can be divided into local exhaust system, general ventilation system and integrated control system. With the general ventilation system, we should have a good prediction tool for testing various appropriate control options. But, until now there are not many studies about how to predict the welding fume concentrations. Especially, the prediction of welding fume concentration is not a very easy task because welding fume is the particulate matters. In this study, we tried to measure CO2 concentrations and welding fume concentrations in a small single room with a small ventilation opening. Using commercially available CFD(Computational Fluid Dynamics) software, we tried to predict CO2 concentrations under the exactly same conditions. Then, we tried to compare the numerical CO2concentrations with the experimental results to know whether we could predict CO2 concentrations. Then we tried to compare CO2 concentrations with experimental welding fume concentrations to know whether we can use the numerical CO2 concentrations to predict the welding fume concentration indirectly.
