ABSTRACT:
A welding wire capable of improving wettability between weld metal and wire surface, thereby providing excellent drawability and weldability in resistance welding of wires is provided. A wire is dipped in an aqueous solution of a sulfide of alkali metal or ammonium sulfide to generate iron sulfide (FeS.sub.2 or FeS) on the surface, whereby the wettability of weld metal to wire surface is improved in the resistance welding of the resulting wires. The S in the iron sulfide is preferably present in an amount of 0.1-20 atomic % as measured by X-ray photoelectron spectroscopy. At least one sulfide of S with an element of Mn, Ti, Cu, Cr, Ni, Al or Zn can be used instead of or in addition to the iron sulfide.
