Abstract. A derivation with axiomatic methods of a perturbative expansion for the
Wightman functions of a relativistic field theory is described. The method
gives also the correlation functions of the fields in KMS states. Using these
results, a scattering formalism for QED is introduced, which does not
involve any infrared divergent quantities.
