Zusammenfassung:	The invention provides a manufacturing method of a wind power tower drum. The manufacturing method comprises the steps of numerical control blanking, edge rolling, longitudinal seam welding, circle returning, pairing, circular seam welding, welding seam nondestructive testing, flange parallelism, coaxiality and planeness detection, corrosion prevention, inner accessory installation and packaging and shipping. The manufacturing method comprises the steps of numerical control blanking, edge rolling, longitudinal seam welding, circle returning, pairing, circular seam welding, welding seam nondestructive testing, flange parallelism, coaxiality and planeness detection, corrosion prevention, inner accessory installation and packaging and shipping. The method has the beneficial effects that a gapless assembly method is adopted for barrel section assembly, the parallelism, coaxiality and planeness of flanges on the two sides of the tower barrel and the overall size of the tower barrel are effectively controlled, and
