Abstract(s)
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.
