  • Ti-base wire rod for forming molten metal
    Patent number: 6582833
    Abstract: A Ti-base wire rod for forming molten metal excellent both in rod feeding smoothness and arc stability is disclosed. A wire rod 301 is composed of Ti metal, and has in the surficial portion including the surface thereof an oxygen enriched layer having an oxygen concentration higher than that in an inner portion. Ratio Tw/Dw of the thickness Tw of the oxygen enriched layer and the diameter Dw of the wire rod is adjusted within a range of 1×10−3 to 1×10−1, and the average oxygen concentration of the oxygen enriched layer is adjusted to 1 wt % or above.
    Type: Grant
