In this note, we prove that for two compatible fuzzy metrics MH and MK on H and K, respectively, there exists a fuzzy metric M on H & Union;K such that M|H=MH and M|K=MK under the conditions that t-norm * is positive and fuzzy metrics MH,MK are strong, or t-norm * is positive and t-norm *, fuzzy metrics MH,MK satisfy the Lipschitz conditions.
