Abstract
In this paper the conditions of pinning of an interface in a 2D Ising ferromagnet with defect connections in a solid-on-solid (SOS) limit are given. It is known that in this case the localisation of interface is formally equivalent to the bound state of quantum particle in temperature dependent effective potential. We show that a wetting transition occurs whenever the couplings on the two sides of the defect are different.
