Butt welding elbow is a kind of pipe fittings which are manufactured by steel hot pressing or forging technology. The connection method is to weld the elbow and steel pipe through butt welding, and use resistance heat to weld the two workpieces along the entire end face at the same time. Elbow materials include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. Based on its radius of curvature, there are two sorts for welding elbow: long radius butt welding elbow and short radius butt welding elbow . The long radius butt welding elbow is equal to 1.5 times the outer diameter of the pipe, ie R=1.5D. The short radius butt welding elbow is equal to the outer diameter of the pipe, ie R=1D.
