The deflection w of the welded plates were measured and the curvatures were determined corresponding to ∂^2w/∂x^2,which were obtained by graphical differentiation of deflection curves. The strains were found from the curvature (ε_x=-z ∂^2w/∂x^2 etc.) and the corresponding stresses in the plastic scope wire determined. The elastic residual strains and stresses were measured and the max. intensity was 20 kg/mm^2,in the case where both edges were welded. The distribution of the residual strains in the plate sections of the welded and permanently deformed portion have been analysed by the bending theory corresponding to similar conditions.
