Headed Concrete Weld Studs also known as Weld Studs, are unthreaded with an upset head. The typical use is for anchoring steel plates and shapes in concrete structures. Our Headed Concrete Weld Studs meets AWS and all other applicable specifications. Weld Studs join a stud and another piece of metal together by heating both parts with an arc. They primarily used to anchor concrete to a steel beam.
Stud welding uses a type of flux called a ferrule, a ceramic ring which concentrates the heat generated, prevents oxidation and retains the molten metal in the weld zone. The ferrule is broken off of the fastener after the weld is completed. This lack of marring on the side opposite the fastener is what differentiates stud welding from other fastening processes. Drawn Arc stud welding permits strong, one-sided welds on base metals with thicknesses starting at 0.048″ (1.2 mm). It produces welds in as little as 0.06 seconds.
Material – Low carbon steel, ASTM A29/A108, 1010-1020. Also available in stainless steel. Typically provided in SS302 though other grades available on request, please contact us for your specific needs.
Length: Length listed is before weld. Stud diameters less than 5/8” will be approximately 1/8” shorter after weld – Stud diameters 5/8” – 3/4” will be approximately 3/16” shorter – Stud diameters 1” will be approximately 1/4” shorter after weld.
