Nelson Stud Welding released its D6L A706 deformed bar stud anchor for concrete anchorage and reinforcement. It is a fully stud-weldable concrete anchor that doesn’t require pre-heating or specialized equipment. The product meets all ASTM A706, ACI 318 and AWS D1.1 requirements. It is available in straight, bent and threaded variations. While hand welding rebar takes an average of two to three minutes, with the A706, operators can reportedly provide a rate of four per minute.
