JS Arc Welding Stud (also known as shear connector or shear stud) is designed to tie concrete to the steel in a composite piece and, acting as an anchor in the concrete against tensile stress, transfers stress to the concrete, by adhesion or by pressure, depending on the structural typology.
JS shear connector is made in Low Carbon Steel (MS) as per AWS D1.1/ISO 13918.

The drawn-arc process, done with the specialist gun, is used for stud welding. Studs are loaded into the gun and on making electrical contact with the work, the tipped end arcs and melts. The duration of the arch is timed to establish a molten state between the end of the stud and the parent material and then the stud is plunged into the weld pool. Ceramic shields are essential parts of the stud welding process. They are designed to encircle the fastener welding, to protect the arc, to limit the weld to a specified zone of the base metal and to contain the molten metal, acting as a mould to shape this metal and to form the weld fillet, also named ‘weld-flash’. It is chipped off when the weld solidifies.
