Abstract: A method of welding using a weld filler additive and a weld filler additive are provided. The method includes the step of welding the component with a filler additive comprising a sufficient amount of each of Co, Cr, Al, Ti, Mo, Fe, B, C, Nb, and Ni, the component including a hard-to-weld base alloy. The method further includes the step of forming an easy-to-weld target alloy on a surface of the component from the welding.
