ABSTRACT:
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.
