Abstract
Disclosed is a method for affixing a metal cladding to a metal base. The method includes: heating the metal cladding and a surface of the metal base with a heating device to create a molten metal pool having molten metal cladding layered upon molten metal base material in the metal base; stabilizing a temperature gradient of the molten metal pool with a laser beam directed into the molten metal pool; and cooling the molten metal pool to affix solidified cladding to the metal base.
