Comparing the Ventilation Methods of Controlling Welding Fume in Large Workshop
Abstract The traditional ventilation method of controlling welding fume in large workshop is the combination of partial ventilation and general ventilation . Because the space is very large ,the traditional ventilation method has some demerits , such as the large ventilation volume and high running cost . In this article , taking an welding workshop as an example , the author use two ventilation methods of general ventilation and push-pull ventilation to control welding fume , and study the merits of push-pull ventilation in controlling welding fume of large workshop .
