RESIDUAL STRESSES PROFILES OF CLADDED AUSTENITIC STAINLESS STEEL BY INCREMENTAL HOLE DRILLING METHOD
Abstract
This work presents the evaluation of the residual stresses profiles in austenitic stainless steel layers cladded by Submerged Arc Welding in ferritic steels. These welding cladded systems are commonly used in process equipments in chemical and petrochemical industries and in nuclear power plants. After the weld cladding process, the samples are subjected to stress relaxation heat treatment and then milled in the austenic surface to obtain the precise tolerances. The objective of this study is to follow the changing of the residual stresses state profiles in the samples. The residual stresses were first evaluated by X ray diffraction technique at the austenitic stainless steel free surface and then by the incremental hole drilling method in the depth. The results show compressive residual stress profiles at all stainless steels surfaces, presenting different values in depth. From the results it seems that the treatment made at 620 degrees C during 1 hour is more efficient.
