A hot wire welding process. An induction coil is used to preheat the filler metal wire prior to its entering the welding puddle / arc region. An induction coil is placed in close proximity to the welding arc. The filler wire is guided and supported by a delivery guide so that the filler wire passes through the center of, and is insulated from, the induction coil.
