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

open access: yesAdvanced Materials Technologies, Volume 11, Issue 16, 21 August 2026.
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 ...

Ediacaran–Cambrian High‐Strain Melt‐Present Deformation of the Archean Charcot Province, East Antarctica

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract The assembly of Gondwana involved several Pan‐African orogens, although their extension into ice‐covered Antarctica remains contentious. Particularly problematic is our understanding of the Kuunga orogenic system in East Antarctica, including its eroded architecture and temporal evolution. The remote Charcot Province, at the easternmost extent

Laser Beam Submerged Arc Hybrid Welding

open access: yesPhysics Procedia, 2011
AbstractThe laser beam submerged arc hybrid welding method originates from the knowledge that, with increasing penetration depth, the laser beam process has a tendency to pore formation in the lower weld regions. The combination with the energy efficient submerged arc process improves the degassing and reduces the tendency to pore formation.

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

open access: yesAdvanced Engineering Materials, Volume 28, Issue 13, 8 July 2026.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Laser Beam Submerged Arc Hybrid Welding

open access: yesPhysics Procedia, 2012
AbstractThe laser beam-submerged arc hybrid welding method originates from the knowledge that, with increasing penetration depth, the laser beam process has a tendency to pore formation in the lower weld regions. The coupling with the energy-efficient submerged-arc process improves degassing and reduces the tendency to pore formation.

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

open access: yesResults 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.
