Abstract

Apparatus and method for purging atmospheric air from a chamber with a gas including means for generating a substantially non-turbulent, laminar flow front of the gas into the chamber with minimal turbulence to displace the atmospheric air in the chamber, the chamber having exhaust means associated therewith to permit the displaced atmospheric air to exit the chamber. The chamber is preferably a welding chamber and the gas is preferably argon.
