© 2015 The Authors. Published by Elsevier Ltd. Results of determination of the longitudinal, lateral and angular deformations in hard faced samples are presented in this paper, as well as the influence of the additional heat treatment on the level of residual deformations. Investigation assumed multi-layer hard facing of the two plates (thicknesses 7.4 and 29 mm) made of steel 55CrMo8. Deformations were measured before the hard facing- after the plates' preparation by grinding, immediately after hard facing and after tempering. The objective was to determine if and how much the additional heat treatment (tempering) influences the level of residual deformations in the hard faced joints.
