BACKGROUND OF THE INVENTION. The present invention relates to a method of producing a weld overlay on a ferrous base metal surface, such as a low alloy steel or cast iron, by electric arc welding, and to a product produced by the method such as a steel mill roll, having improved machinability, metal-to-metal wear resistance and corrosion resistance.
An alloy characterized by its highly abrasive resistant qualities which render it particularly suitable for use as the material from which to fabricate the external surface of a grinding, i.e., pulverizer, roll (18) of the type that is designed to be employed in a bowl mill (10) so as to be operative therein for purposes of effecting the pulverization of a material such as coal through the ...

Cladding or Weld Overlay (WOL) Cladding operations deposit weld metal on the surface of the base material to extend the service life of the part, while most arc welding processes are used to join two pieces of base material. Cladding can be used to enhance the wear resistance or corrosion resistance of a base material.

One technology comes from a company, Cladding Technology, whose primary business was a patented resurfacing process that utilizes a special matrix of tungsten carbide and weld overlay material applied to the high-wear areas of grinding rolls for vertical spindle mill pulverizers. The method of application of the tungsten carbide matrix is unique.
The BTM is a low-speed mill that primarily grinds coal by impact and attrition. The VRM is a medium- speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed
