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.
