A new concept is proposed to evaluate residual deformation and residual stresses due to welding in a verificational manner. The proposed method is as follows. Displacements are measured through digital image pictures of a weldment before and after the weld and eigen-stains are evaluated by the inverse analysis. Then displacements and residual stresses are estimated by the forward analysis. The outcomes from this method can be directly applicable to subsequent FEM analysis in design.
