In the present work an attempt has been made to determine residual stresses in weldments both by a non destructive non-conventional method based on directional hardness (indentation method) testing and by the destructive conventional method of stress relaxation. Residual stresses thus obtained in both the methods are compared; the causes of variation of stresses are explained.

Abstract


In the present work an attempt has been made to determine residual stresses in weldments both by a non destructive non-conventional method based on directional hardness (indentation method) testing and by the destructive conventional method of stress relaxation. Residual stresses thus obtained in both the methods are compared; the causes of variation of stresses are explained.
