Dust Control Measures for Electric Welding in Small Factories

Object Most small units do not have any dust control facilities for welding. Large amount of welding fumes and fine dusts seriously injure the worker's health. In order to provide the appropriate dust control measures for electric welding in small units, a special investigation was carried out.Methods Based on the results of surveys and tests at the welding work place in different factories, comprehensive dust control measures(which include: process technology improvement, local exhaust ventilation, personal protection etc.) were put forward.Results A designed scherme where the dust concentrations at work place would meet the hygienic standard, and the effluent from the dust collector of bag filter met the emission standard, was used successfully in many units.Conclusion The ventilation design and data provided by this paper has scientific basis, and it is easy for the technicians of the small units to handle, can be properly used in practice.
