Abstract : The effects of longitudinally welded seams and webs on large steel tensile specimens were investigated. Some interesting data were obtained on the nature and mode of propagation of rupture in the specimens. These data were secured by means of a motion picture camera. The value of energy absorbed was computed for each specimen. Longitudinal weld and web metal had little effect on the strength of medium steel, but a moderate reduction in ductility resulted. The strength of high tensile and of special treatment steel was reduced slightly by the presence of longitudinal weld and web metal, but there were erratic variations in the ductility of these steels. The medium steel specimens absorbed more energy than did the high tensile and special treatment steel specimens. However, this difference was less pronounced where the high tensile steel and special treatment steel specimens had medium steel welded webs.
