Abstract
The apparatus includes a molten material cladding apparatus comprising a crucible and a molten material dispensing tool engaged therewith. The crucible and molten material dispensing tool form a chamber to retain molten material, the molten material flowing through passageways in the molten material dispensing tool to form menisci in a bore thereof. An extrusion passing through the molten material dispensing tool punctures the menisci, wherein molten material flows through the molten material dispensing tool and clads the outer surface of the extruded product passing therethrough. By using menisci of molten material, a smooth surfaced, uniform thickness clad product is produced having a wide range of cladding thicknesses.
