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

GMAW shielding gas flow optimisation by refinement of nozzle geometry [PDF]
, 2013 With an ongoing demand to improve the efficiency of the gas metal arc welding process, steps are being taken to reduce the shielding gas consumption. However, sufficient shielding gas coverage of the weld region is essential for the generation of high ...

Spatter matters – distinguishing primary (eruptive) and secondary (non-eruptive) spatter deposits [PDF]
Scientific Reports, 2018 AbstractSpatter is a common pyroclastic product of hawaiian fountaining, which typically forms vent-proximal ramparts or cones. Based on textural characteristics and field relations of spatter from the 1969 Mauna Ulu eruption of Kīlauea, Hawai’i, three spatter types were identified: (1) Primary spatter deposited as spatter ramparts and isolated cones ...

Materials & Design, 2022 The uniformity of a recoated powder layer affects the performance of parts manufactured by SLM directly, while it is related to the characteristics of spatters. The small spatter moves pretty fast, while the low optical transmittance in the spectrum of a

Material Reuse in Laser Powder Bed Fusion: Side Effects of the Laser—Metal Powder Interaction
Metals, 2020 Metal additive manufacturing is changing the way in which engineers and designers model the production of three-dimensional (3D) objects, with rapid growth seen in recent years. Laser powder bed fusion (LPBF) is the most used metal additive manufacturing

Geometric Algebra Model of Distributed Representations [PDF]
, 2010 Formalism based on GA is an alternative to distributed representation models developed so far --- Smolensky's tensor product, Holographic Reduced Representations (HRR) and Binary Spatter Code (BSC).

Materials & Design, 2023 Complex phenomena occur at the laser spot in powder bed fusion with laser beam (PBF-LB); thus, it creates several large process-parameter spaces such as power and scanning speed, along with many others. To allow for high-throughput parameter exploration,
