Solution of the axis-symmetric contact task of thermo-elasticity of the hot cylinder circular punch stress on the elastic isotropic layer taking into account a non-ideal heat contact between punch and layer is built. Formulas for determination of the temperature field and normal stress in the contact area are obtained. The effect of the contact elasticity on the temperature and normal stress distribution is investigated. Investigation was made on the influence of the contact conductivity on distributing of the temperature fields and normal stress in the area of contact of two bodies.
