Disclosed is a manufacturing method for a tower damper. The manufacturing method is characterized by comprising the following steps of (1) material selection, (2) production preparation, (3) steel blanking, (4) hole drilling, (5) welding, (6) manufacturing deviation examining, (7) rust removal and coating, (8) marking, (9) workshop assembly, and (10) packing and transportation. The manufacturing method for the tower damper has the advantage that the hole drilling precision is high, the influence of welding deformation is eliminated, the component machining precision is high, a factory simulation test is conducted, and assembly in a narrow space is ensured.
