Disclosed herein is a manufacturing method, excellent in wire drawability, of a seamed flux-cored welding wire having both favorable feedability and low hydrogen content characteristic. The method for manufacturing a seamed flux-cored wire, comprises the steps of: drawing a tube-like formed wire including a flux filled therein using a lubricant; removing the lubricant from the drawn wire by a physical means; and coating a lubricant (coating an oil) for wire feeding on the wire surface. The respective steps are carried out in an in-line manner. In the wire drawing step, a wire drawing lubricant containing a sulfur-bearing high-pressure lubricant is used, and the overall wire drawing from the tube-like formed wire to a roughly product-diameter wire is carried out by means of a roller die.

A lubricating oil and/or lubricating particles are chemically combined with a wire surface through the one or more hydrocarbon compounds. The total amount of the hydrocarbon compounds, and a lubricating oil and/or lubricating particles deposited on the wire surface is in the range of 0.1 to 5 g per 10 kg of the wire.
摘要:
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.
