Abstract
An apparatus and system for preheating and removing surface oxidation of welding wire using electric arcs one via one or more tungsten electrodes is disclosed. The preheating and cleaning electric arcs may occur between tungsten electrodes, or between one or more tungsten electrodes and welding wire. Electric arc preheating of welding wire allows increased efficiency and deposition rates.
Claims19
An apparatus for preheating welding wire, the apparatus comprising:
- a first tungsten electrode and a second tungsten electrode configured to preheat welding wire via electric arc preheating to the wire prior to delivery of the welding wire to a welding arc.
A system for preheating welding wire, the system comprising:
- a power source;
- a first tungsten electrode electrically connected to the power source;
- and
- a second tungsten electrode electrically connected to the power source;
- wherein the first tungsten electrode and the second tungsten electrode are configured to generate an electric arc through which a welding wire travels to thereby preheat the welding wire via the electric arc.
