PURPOSE: To realize sound welding not having blow hole, crack, etc., in the case of porous ferrous sintered material, in particular, the sintered material in which oxide and water content are stuck/permeated on surface or inside by specifying the composition of welding material. CONSTITUTION: In the welding material used for welding between ferrous sintered materials or between ferrous sintered material and steel, a welding material for welding sintered material, in which a composition by weight in total filler metal satisfies the following requirement, is disclosed. The composition consists of, by weight, 0.05-0.4% C, 0.1-1.2% Si, 0.2-10% Mn, 0.1-2% Al and/or Ti, 5-20% one or more kinds among CaCO3 , BaCO3 , MgCO3 , LiCo3 , and the balance essentially Fe. |
