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

Metal Waste Dusts from Mechanical Workings – Explosibility Parameters Investigation
Chemical Engineering Transactions, 2018 The reactivity of metal scraps or fine particles, typical residual wastes of mechanical workings, is significantly high to cause violent deflagration when particles disperse in the air in the form of clouds.

Time-resolved imaging of electron beam powder bed fusion using an X-ray microscope optimized for white beam radiation. [PDF]
J Synchrotron RadiatA high‐speed X‐ray microscope design optimized for white beam synchrotron radiation enables real‐time in situ imaging of crack dynamics during electron beam powder bed fusion (PBF‐EB) of high‐Z materials. With high temporal resolution and 10 µm spatial resolution, the system reveals previously unobservable crack evolution behavior in Ni‐based ...

Advanced Engineering Materials, EarlyView.Plasma‐assisted hybrid friction stir welding of dissimilar AlCu joints employs localized plasma preheating to balance heat input and enhance plastic flow. The optimized process reduces axial force by up to 35%, refines the microstructure, and achieves ≈96% joint efficiency.
