• Description:
  The National Institute for Occupational Safety and Health (NIOSH) is currently conducting research on the effectiveness of various engineering controls to reduce arc welding fume emissions. Most control measures observed in the workplace employ either general or local ventilation methods, such as canopy hoods and fume extraction guns. Recent research interest has focused on the ability of process modifications to eliminate or reduce the need for ventilation during gas metal arc welding (GMAW) operations. This paper relates the detals of an in-depth study conducted of GMAW operations, at an agricultural and construction machinery manufacturer. This company was distinct from other sites surveyed because many of the welders used pulsed inverter, rather than conventional, welding power sources. According to recent literature, pulsed gas metal arc welding can result in lower fume levels than conventional gas metal arc welding because of a controlled droplet size and a lower average welding current.
