ABSTRACT:
Methods of hard facing iron or steel articles by a submerged arc welding process are described. Specifically, an iron or steel rolling mill roll arbor is hard faced by rotating the arbor about its longitudinal axis and traversing a welding head parallel to said axis to deposit a spiral bead of weld metal on the arbor for subsequent heat treatment and machining. Different consumable electrodes and fluxes are chosen to deposit a desired hard facing on the arbor.
