Welding fumes formation. V. Formation of final agglomerates.

Physics of Aerodisperse Systems, 2014
The dusty plasma behavior is studied in the process of coagulation of the primary particles, which are formed as a result of the nucleation and nuclei growth in the condensable hightemperature vapors. The study is concentrated to the example of the thermal plasma formed in the welding fume in the arc welding process where the electrodes covered with ...

Benchmarking Coaxial and Angular Optical Emission Spectroscopy With Recommendations for Reliable Compositional In Situ Monitoring During Laser Powder Bed Fusion

Advanced Materials Technologies, EarlyView.
ABSTRACT Real‐time insight into local chemistry is critical for reliable part quality in additive manufacturing, especially laser powder bed fusion (PBF‑LB/M), where rapid thermal cycles and localized evaporation can undermine part performance. Optical emission spectroscopy (OES) offers non‑intrusive, in situ plume monitoring, but detection geometry ...

Multilayer Biobased Poly(ethylene furanoate)/Graphene Oxide Nanofibrous Membranes With Directional Water Transport for Efficient Microplastics Filtration

Advanced Materials Technologies, EarlyView.
A self‐assembled multilayer biobased PEF/GO nanofibrous membrane was developed by electrospinning for efficient PLA microplastics (MPs) filtration. The membrane combines superhydrophilicity, directional water transport, mechanical robustness, and a synergistic size‐exclusion interception and electrostatic repulsion MPs separation mechanism, enabling ...

Investigation of humping defect formation in a lap joint at a high-speed hybrid laser-GMA welding

Results in Physics, 2019
Productivity rise can be realized at high-speed welding, but in a practice, the constraints emanate from the tolerance welding speed limit beyond which generate humping defects and the likes.

Effect of Welding Current on High Speed Welding Bead Formation in Tandem Pulsed GMA Welding Process

QUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 2005
In tandem pulsed GMA welding the stabilization of accumulated molten metal between the leading arc and the trailing arc, the presence of enough molten metal below the trailing arc, and the reduced velocity of molten metal flow towards the rear part of the weld pool are essential to improve the maximum welding speed.
