    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a welding material capable of overcoming all of six problems including a problem that cracking of an extrusion-molded product often occurs during a defatting step or a sintering step and a problem that the extrusion-molded product is disrupted readily.SOLUTION: The method for producing the welding material comprises, in the following order: a compound production step S2 of kneading alloy powder containing first alloy powder having a first average particle diameter and second alloy powder having a second average particle diameter, a water-soluble binder and water to produce a compound; a drying step S4; an extrusion step S6; a defatting step S8 of heating the extrusion-molded product to a predetermined temperature equal to or higher than 400°C; a C-O reaction step S10 of heating the extrusion-molded product to a predetermined temperature that ranges from 950°C-1150°C in a vacuum atmosphere; and a sintering step S12 of heating the extrusion-molded product to a predetermined temperature that ranges from 1200°C-1350°C in a nitrogen gas atmosphere to produce the welding material.
