ABSTRACT:
There is provided an improved basic coated welding rod for downhand welding of fixed pipes. The coating contains by weight on a dry basis 22 to 28% of calcium carbonate, 1.5 to 3% of calcium fluoride, 7 to 14% of titanium dioxide, 35 to 55% of iron, and 5 to 25% of at least one element selected from the group consisting of chromium, manganese, silicon, nickel and molybdenum. The ratio of the coated welding rod diameter to the core wire diameter is between 1.45:1 and 1.70:1. Preferably the ratio of calcium carbonate to calcium fluoride in the coating is between 10:1 and 20:1. Advantageously, at least 35% of the iron in the coating is iron powder.
