Abstract

A stud weldable rebar includes a steel bar comprised of a material composition confirming to ASTM 706 which extends along an axis A from a first end to a second end. The steel bar includes a base portion disposed adjacent the first end which has a base diameter Dto define a base cross-sectional area of the base portion. The steel bar also includes an upset portion disposed adjacent the second end which has an upset diameter Dbeing greater than said base diameter Dto define an upset cross-sectional area of said upset portion. The material composition of the steel bar is restricted to a carbon equivalency between 0.31 and 0.43, and the upset cross-sectional area is approximately 13.5% to 22.5% greater than the base cross-sectional area to provide A706 rebar that surprisingly meets both the AWS D1.1 and ACI 318 standards after stud welding.
