Abstract
Disclosed are methods of facing a surface of a weldable iron based material with a consumable iron based electrode and alloy forming elements by creating an electric arc between the electrode and the surface of the weldable base material effective to form a weld puddle of which the weldable base material provides from about 35% to about 80% by weight, and preferably a major portion, of the weld puddle formed by the electrode and the base plate and by depositing and melting a predetermined quantity of alloy forming elements in the weld puddle to form an alloy abrasion resistant or corrosion resistant facing. Also disclosed are plates having abrasion or corrosion resistant surfaces in which from about 35% to about 80% and preferably a major portion of the weld puddle formed by the electrode and the base material is the weldable iron based material.
