摘要: A wire for gas metal arc welding containing 0.01 to 0.06 wt % of C, 0.10 to 0.60 wt % of Si, 0.9 to 3.1 wt % of Mn, 0.7 to 2.0 wt % of Cr, 0.005 to 0.06% of Ti, not greater than 0.08 wt % of Al and if necessary, 0.05 to 0.30 wt % of Cu, and the balance of Fe and unavoidable impurities. This wire improves the selective corrosion resistance and the low temperature toughness of the resulting weld metal, and is particularly suitable for circumferential welding of line pipes for transporting CO.sub.2 -containing petroleum, natural gases or CO.sub.2.
