Systematic study of effect of cross-drafts and nozzle diameter on shield gas coverage [PDF]

, 2013
A shield gas flow rate of 15–20 L min21 is typically specified in metal inert gas welding, but is often adjusted to as high as 36 L min21 by welders in practice. Not only is this overuse of shield gas wasteful, but uncontrolled high gas flows can lead to
