• Effect of relative size of weld metal on mechanical behavior of welded joints is investigated in connection with the properties of weld and base metals. Welded joints are idealized as round bar models consisting of base metals and a soft interlayer. They are made by flash-butt welding using medium carbon steels and a low carbon steel. Tensile strength of the joints is raised by the decrease in the relative thickness of soft interlayer to specimen diameter and the difference in strength between base metals and soft interlayer. Brittle fractures with rim of cleavage facets are observed for sufficiently small values of relative thickness. Reduction in area is minimum at a certain value of relative thickness.
