摘要： 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.
