STUDY OF THE LEVEL AND DISTRIBUTION OF STRESS IN SPECIAL WELDING SAMPLES OF 30-MM THICK HIGH-TENSILE STEEL
The paper deals with an experimental investigation of the level and distribution of residual welding strains and stresses in special welding specimens of 30-mm thick perlite high-tensile steel. The multi-wave nature of residual stresses was demonstrated, with significant stress gradients occurring in sections perpendicular to welds and major tensile-stress peaks in weld zones. The question of the effect of filler metal on the stressed condition of weldments was not entirely elucidated and requires further study, but the use of low-alloy filler metals results in greater rigidity of the structure. Maximum stress levels obtained with different filler metals are listed for manual and automatic welding. Order from: BSRA as No. 46,868.
