Abstract:
Welding has become an indispensable metal joining process in fabrication industries. Welding fumes evolved during welding process not only pollute environment, but also cause occupational health problem to the welders.
The National Institute for Occupational Safety and Health (NIOSH) defines welding fumes as potential occupational carcinogens. Welding fumes require more filtrations practically than any other application in industry, so strategy was developed to save environment as well as workers. Fumes with sub micron particle size can be cleaned by filters, fabric collectors, electrostatic precipitator, cyclone separators, and spray towers for purification. A fume extraction system employing ESP (Electro Static Precipitator) is high compare with other air cleaning devices.
This paper focuses on the effectiveness of the fume extractor with an Electrostatic Precipitator used in a welding environment.
