Abstract: A cladding system and method for applying a cladding to a power generation system component including a first weld bead, a second weld and a filler bead. The first weld is deposited on the surface with a first energy source and solidified to form a first weld bead. The second weld is deposited on the surface adjacent to the first weld bead with the first energy source, wherein depositing the second weld creates a surface depression between the first weld bead and second weld. The filler bead is simultaneously deposited in the surface depression with a second energy source while depositing the second weld bead. The second weld and the filler bead are solidified to form the cladding bead.

Abstract: A method of fabricating a component and a fabricated component are disclosed. The method includes depositing a material to a component and manipulating the material to form a boundary region and a filler region for desired properties. The component includes the boundary region and the filler region, thereby having the desired properties.

Abstract: A method of establishing filler metal composition for joining components includes determining an initial desired filler metal chemistry, adjoining a first filler rod having a first portion of the desired filler metal chemistry with a second filler rod having a second portion of the desired filler metal chemistry to form a test filler rod, joining a first component formed from a first material to a second component formed from a second material at a weld joint with the test filler rod providing a filler metal portion of the weld joint, and testing the weld joint for desired mechanical, chemical, and weldability properties to establish a desired filler metal composition.

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.
