weld overlay (Weld overlay is a welding process where one or more metals with specific characteristics are applied to a base metal to improve desirable properties or to restore the original dimension of the component. Weld overlay may also be referred to as cladding, hard facing, weld cladding or weld overlay cladding. Instead of general welding which is joining two pieces of material together, weld overlay applies a corrosive resistant or hard facing layer onto the parent material. Kenny Gray) |
