Simple monitoring of welding spatter for quantification and observation using a mobile phone

Advances in Mechanical Engineering, 2017
Unstable welding arcs can cause the scattering of molten welding pools, a phenomenon known as welding spatter. Spatter deteriorates product quality and necessitates inefficient secondary processes and their associated costs for its removal.

Pure titanium fabrication with spatter-less selective laser melting in vacuum

Results in Optics, 2021
Selective laser melting (SLM), which is an additive manufacturing technology, is attractive due to its ability to freely form shapes. SLM forms a 3D material by building it layer-by-layer from a metal powder. However, some issues have yet to be resolved,

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

Advanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...
