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 ...

A feasible operational parameter window for enhancement of welding speed in friction stir welding of 2195-T8 Al–Li alloy

Science and Technology of Welding and Joining, 2023
The improvement of the welding speed becomes extraordinarily difficult for the friction stir welding (FSW) of Al–Li alloys with medium thickness (5–10 mm). In this study, 2195-T8 Al alloy plates with a thickness of 6 mm were subjected to FSW under different welding speeds of 200–800 mm/min with the objective of seeking an optimised welding parameter ...
