The influence of applied clad procedure as well as heat treatment bv annealing on level and nature of residual stresses was researched. The relaxed deformation measurement on clad plate surfaces was performed by applying centre-hole drilling method using special measuring electrical resistance strain gauges (rosettes). After performed measuring, size and nature of residual stresses were determined using analytical method. Depending of residual stresses on depth of drilled blind- hole is studied.
