Gas metal arc welding of metal-polymer-metal sheets

Tribology and Materials, 2022
Metal-polymer-metal (MPM) sheets are sandwich panels used for housings of large industrial electric motors and generators, vehicle body panels, flooring, various bulkheads, wheel arching, engine and gearbox shielding, etc. Their main advantage over classic steel panels in form of plates is their acoustic dampening properties. Joining of such plating is

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 ...
