1. A support structure for a wind turbine, comprising:
at least two segments which are connected to one another by means of a circular weld seam in such a manner that longitudinal axes thereof run substantially collinearly to one another,
wherein at least one of the segments is a cylindrical pipe element which has at least two mutually facing joining surfaces which are connected to one another at least in sections,
wherein the joining surfaces are connected to one another by means of at least one welded joint, wherein a thickness of the welded joint at least in sections is smaller than a thickness of the joining surfaces such that the welded joint is not coextensive with the joining surfaces.
