In this thesis we investigate three approaches to generating new solutions to low energy string theory. The first one consists in gauging WZW models. We construct a gauged extension of a model first introduced by Witten and Nappi. Then we look at Garfinkle's wave generating technique and apply it on a known five-dimensional black string to generate a new family of solutions. We investigate their properties with a special emphasis on singularities. Finally, in the last part, we study O(d, d + p) transformations and duality and we explore the effect of gauge transformations on those transformations. With the latter, we are able to answer a question raised by Burgess, Myers and Quevedo on this issue.
