Under the DURIP Grant FA9550-17-1-0444, Acquisition of a precision Fronius Cold Metal Transfer-Advanced, CMT-Advanced, Gas Metal Arc wire GMAW welding system, PSU acquired and installed the system with integration of a Fronius CMT-Advanced unit with a Yaskawa Motoman 6-axis robot and a 2 axis coordinated positioner. The final report contains the system installation, performance, and further project plans with the system. The high deposition rate CMT-advanced system will contribute in the area of wire arc additive manufacturing with robotic control, and Cold Metal Transfer CMT additive manufacturing AM. The sync-up with the existing Electrospark ESD micro deposition ratetechnology has been tested and the initial results posed mechanically and chemically stable multi-layered structures with localized property variation, which can be applied to multi-scale additive manufacturing applications.
