THE SIGNIFICANCE OF RESIDUAL WELDING STRESSES--SOME EXPERIMENTAL RESULTS AND PRACTICAL EXPERIENCE IN A SHIPYARD
The paper summarizes experimental work carried out in the laboratory of Kockums Shipyard to determine the influence of residual stresses in welded ship and machinery structures. Following an outline of the measurement methods employed, the individual factors contributing towards failure are discussed under the following headings: brittle fracture, distortion, vibration, overstressing, heat treatment, hydrogen cracking, stress corrosion cracking, and, in conclusion, the relationship between residual stresses and fatigue life. From the results of the study it is concluded that distortion and dimensional stability are the most important of these factors, which may, in some critical structures, justify stress relief heat treatment.
