Sattarifar Mechanical Faculty, Amirkabir University of Technology, Tehran, Iran Journal Article 2015 11 20 Weld residual stress is one of the most sensitive issues in the safety and reliability of<br />structures such as nuclear reactor components. In order to prevent the corrosion caused by corrosive<br />environments, the inner surface of containers made of carbon steel, is cladded in a layer of austenitic<br />stainless steel. In this study, a steel plate of carbon steel A516-G70, will be cladded by the shielded metal<br />arc welding method. In order to validate the results, hole drilling method is used to determine residual<br />stresses. Finally, the residual stresses in samples with two and three layer cladding are examined. By<br />giving the sources of error in testing, the results have a relatively good compliance. The results indicate<br />that, the maximum amount of residual stresses in the clad layer, are tensile and in the stress limit, it is<br />in submission of base metal and cladding layer. Also, by increasing the number of layers in the cladding<br />layer thickness and steel plate, residual stresses are reduced. However, at the surface of the cladding<br />layer stresses have inconsiderable changes. And on the border between the cladding layer and the plate,<br />residual stress increases by increasing the number of layers.
