Abstract
Abstract A consumable wire guide electrode for producing a high alloying effect on the weld deposit includes spaced inner and outer tubes defining a void therebetween filled with an alloying material and binder, the bore of the inner tube serving as a guide for the feed of a continuous wire electrode therethrough. The outer tube is advantageously exteriorly coated with flux such that as the wire and guide are consumed by an electric arc, a pool of alloyed weld metal with flux floating on the top is produced.
