The American Welding Society (AWS D 1.4) sets out the practices for welding rebar in the U.S. Without special consideration, the only rebar that is ready to weld is W grade (Low-alloy — A706). Rebar that is not produced to the ASTM A706 specification is generally not suitable for welding without calculating the "carbon-equivalent." Material with a carbon-equivalent of less than 0.55 can be welded. (AWS D1.4)
