• Description:
  An experimental investigation was conducted to define satisfactory criteria for the control of welding and cutting fumes using local exhaust ventilation methods. The criteria for effectiveness of a system was its ability to reduce breathing zone metallic fume concentrations below the mixture threshold limit value. The following three process-base plate combinations were selected for local exhaust ventilation control studies: shielded manual metal arc welding on carbon steel, shielded manual metal arc welding on stainless steel, and gas shielded arc welding on carbon steel. A crossdraft ventilation table was designed and fabricated for use with the gas shielded process. In addition, a low volume-high velocity fume extracting welding gun was evaluated in conjunction with this process. A free-standing rectangular hood was applied to the covered electrode processes.
