Automatic fixed position pipe welding is carried out by gas-shielded electric arc welding with a novel flux-cored electrode wire having a low-carbon sheel sheath containing a core filling of, by weight, 16-17 percent ferro manganese, 10-11 percent ferro silicon, 1-4 percent manganous oxide, 1/2-1 percent potassium aluminum fluoride, and the balance rutile. The wire exterior is shiny and metallic-appearing, and the wire is configured to have folded-in edges.

A novel flux-cored welding wire for gas-shielded electric arc welding is described characterized by a shiny, metallic-appearing surface on a low carbon steel sheath and containing within its core as essential flux ingredients 6-20% ferro manganese, 6-20% ferro silicon, 1-20% manganous oxide, 1/2-5% of a flouride compound, and the balance rutile. The wire is especially useful in out-of-position welding to produce sound welds combining good strength and high notch toughness at subzero temperatures.
