| Abstract |
The objective of this research was to establish whether efficient welding fume capture can be achieved using local exhaust ventilation (LEV) while at the same time maintaining weld metal integrity. It was carried out in three phases. Phase 1 provided the information necessary to develop an experimental plan. Phase 2 determined the maximum cross flow velocity of air that could be tolerated before the onset of weld metal porosity during gas shielded arc welding using parameters defined in Phase 1. Finally, Phase 3 measured capture efficiencies for a range of LEV hoods positioned at various distances and orientations to the welding arc. Findings are discussed. It is concluded that when using standard welding parameters, satisfactory fume extraction was possible without compromising the weld integrity. |
