Abstract
A method and apparatus for applying filler material to a workpiece in conjunction with a heat producing means, to deposit a heating/molten pool region on the workpiece; wherein the filler wire is introduced into the pool region in a reciprocating manner which alternately advances an end of the filler wire into and out of the pool region; and wherein the heat produced by the heat producing means is varied so that peak heating pulses are initiated and maintained when the filler wire contacts the pool region, and so that the heat producing means maintains a lower, background level when the filler wire is withdrawn from the pool region.
