We consider the family of smooth embedded surfaces of revolution in ae(3) having two concentric circles contained in two parallel planes of ae(3) as boundary. Minimizing the Willmore functional within this class of surfaces we prove the existence of smooth axi-symmetric Willmore surfaces having these circles as boundary. When the radii of the circles tend to zero we prove convergence of these solutions to the round sphere.
