Abstract: An energy storage module (ESM) is provided for connecting to a welding or cutting machine (WCM). The ESM has a controller for connecting to a communication link (CM) to communicate with the WCM when the ESM is connected to the WCM. The ESM also has a battery pack to store electrical energy and output DC electrical power to be used by the WCM, under control of the controller. Electrical input power provided to the WCM from an electrical grid or a renewable energy source during a welding or cutting operation can be supplemented or replaced by the DC electrical power from the ESM. The ESM further has regulation circuitry to regulate the DC electrical power output from the battery pack. The controller controls the regulation circuitry based on identification data received over the CM from the WCM to regulate the DC electrical power to be electrically compatible with the WCM.

Abstract: Embodiments of an integrated laser hot wire deposition head are disclosed. In one embodiment, the deposition head includes a structural frame, a laser process sub-system, a wire feeding device, and a contact tube. The laser process sub-system is mounted within the structural frame to deliver a single beam path laser beam in a longitudinally-oriented direction toward a substrate or a part to be additively manufactured. The wire feeding device and contact tube are mounted within the frame to feed a consumable filler wire toward the substrate or part at an angle with respect to the longitudinally-oriented direction. The deposition head can be moved omni-directionally with respect to the substrate or the part, under the guidance of a motion control system, to additively manufacture the part without having to angularly change an orientation of the single beam path laser beam from the longitudinally-oriented direction or rotate the deposition head.
