Hardfacing

From Wikipedia, the free encyclopedia

Hardfacing is a metalworking process where harder or tougher material is applied to a base metal. It is welded to the base material, and is generally takes the form of specialized electrodes for arc welding or filler rod for oxyacetylene and TIG welding.

Hardfacing may be applied to a new part during its production, or it may be used to restore a worn-down surface.
