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

, 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

Impact Analysis of Welding Sequence to Reduce Weld Deformation in Aluminum Hulls

Journal of Marine Science and Engineering
Aluminum hulls, which are preferred in the marine industry due to their durability, corrosion resistance, and lightweight properties, face serious challenges due to thermal deformation during welding. This study aims to predict and minimize transverse deformations due to welding sequences for a transverse model in the lower part of an aluminum hull. To
