Abstract (EN): The samples studied in this paper were carried out using carbon steel plates, cladded on one of the faces with stainless steel filler metals by submerged arc welding (SAW). After cladding, the samples were submitted to post-weld heat treatments under different conditions and then stainless steel coating surfaces were milled and mechanically polished, as in the industrial application. The residual stress analysis was performed by X-ray diffraction (XRD) and incremental hole-drilling methods (IHD). The residual stress profiles showed different values in-depth in each sample, depending on the heat treatment. The hole-drilling method was applied in several points of each stainless steel sample surface and the results presented similar profiles of evolution. However, compressive stresses increase when the heat treatment temperature rises.
