Additional manufacturing methods and systems using pulsed heating signals using high energy sources and thermal wires

摘要

A method and system to manufacture workpieces employing a high intensity energy source that irradiates a surface of a workpiece to create a puddle and at least one resistively heated wire which is heated to at or near its melting temperature and deposited into the puddle as droplets. Preferably, a wire feeding device feeds the wire to the puddle, and a power supply supplies a heating signal to the wire where the heating signal comprises a plurality of current pulses and where each of the current pulses creates a molten droplet on a distal end of the wire which is deposited into the puddle.
