Abstract
A welding enclosure includes a central work chamber; a plurality of horizontally spaced welding work stations within the central work chamber; an exhaust chamber beneath and generally coextensive with the central work chamber; a floor over the exhaust chamber, underlying and substantially coextensive with the central work chamber, and including vents operative to allow air to pass through the floor between the central work chamber and exhaust chamber; an exhaust fan for exhausting air from the exhaust chamber; a blower arranged to establish a positive air pressure in the plenum chamber; and a ceiling over and substantial coextensive with the central work chamber, underlying the plenum chamber, and including air registers operative to pass air downwardly through the ceiling from the plenum into the central work chamber for passage downwardly through the central work chamber and through the floor vents into the exhaust chamber for removal by the exhaust fan. The various parameters of the enclosure assembly are selected to establish a steady substantially laminar downward flow of air over substantially the entire horizontal area of the central work chamber at a velocity sufficient to …
