| Resumen |
A mathematical analysis of the aerodynamic conditions to be met by local exhaust ventilation equipment for the removal of welding fume in the presence of limiting surfaces is followed by a description of an exhaust ventilation hood mounted on a welding torch for inert gas (CO2) welding. Prototype testing of this device showed the optimal diameter definition for the hood to be 70-80mm for a distance of 80mm between it and the welding point. Fume is exhausted through a flexible tube, the aerodynamic resistance of which is easy to determine. Removal efficiency is 90-95%, and saving in energy consumption is considerable compared to conventional local exhaust ventilation systems. |
