To provide a method for producing a highly reliable welding joint, regarding the production of a weld zone in a structure, in which welding defects such as a penetration fault are suppressed, and further, the weld zone has excellent material properties such as stress corrosion crack resistance.
In the method for producing a welding joint by welding metal members, the material component of a welding wire used upon the welding of the metal members is controlled so that the content of sulfur (S) is 0.004 to 0.010%, and also, the content of ferrite based upon a dilong chart is 10 to 15%. According to this invention, regarding welding joint production in a welded structure including piping or the like, the method for producing a highly reliable welding joint using a TIG welding wire for an initial layer in which welding defects such as a penetration fault are suppressed, and further having excellent stress corrosion crack resistance can be provided.
