Gas metal arc welding (GMAW) wire arc additive manufacturing (WAAM) processes use inert shielding to protect the weld arc during material deposition, but do not protect the trailing bead, which can lead to weld issues varying from low finish quality to diminished material prop
Adhesives for metal parts typically are liquid-based which require complex processing. This technology is a hot melt adhesive that is mixed and applied in a solid form and after the heating and cooling cycle creates strong bonds with the substrates in a matter of seconds.
As additive manufacturing technologies advance and 3D-printers get larger, there is a constant need for larger extruders with higher throughput to construct larger objects at reasonable time.
The co-processing of cathode and composite electrolyte for solid state polymer batteries has been developed. A traditional uncalendared cathode of e.g.
ORNL has developed a new hybrid additive manufacturing technique to create complex three-dimensional shapes like air foils and wind generator blades much more quickly.
Electrical utility substations are wired with intelligent electronic devices (IEDs), such as protective relays, power meters, and communication switches.
