PROBLEM TO BE SOLVED: To provide a nickel-based weld filler and a method of welding a hard-to-weld alloy using a nickel-based weld filler.SOLUTION: The invention provides a method of welding using a weld filler, and the weld filler. The method includes the step of welding a component with a weld filler comprising a sufficient amount of each of W, 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 step.SELECTED DRAWING: Figure 1 【課題】ニッケル基溶加材、およびニッケル基溶加材を使用して溶接困難な合金を溶接する方法を提供すること。【解決手段】溶加材を使って溶接する方法、および溶加材が提供される。本方法は、構成部品を、十分な量のＷ、Ｃｏ、Ｃｒ、Ａｌ、Ｔｉ、Ｍｏ、Ｆｅ、Ｂ、Ｃ、Ｎｂ、およびＮｉそれぞれを含む溶加材と溶接するステップを含み、この構成部品は溶接困難なベース合金を含む。本方法は、溶接するステップから、構成部品の表面に溶接容易な目標合金を形成するステップをさらに含む。【選択図】図１
