  • Patent number: 5491320
    Abstract: A method and apparatus for ventilating a robotic welding enclosure. A hood is positioned on the welding head structure of each robotic welder and includes an annular skirt portion in surrounding relation to the feed axis of the welding materials. The skirt defines a lower opening which is positioned proximate the welding locus so as to define a capture chamber extending upwardly from the skirt portion opening in surrounding relation to the feed axis of the welding materials. A vacuum condition is created in the capture chamber so as to suck the gaseous welding bi-products generated at the welding locus upwardly into the capture chamber from where the gases are moved via a flexible conduit to an overhead duct which carries the welding products to a location outside the welding enclosure for discharge.

  • Patent number: 5410120
    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.
