Welding Stud/Nelson Stud AWS D1.1/1.5

Technically called weld studs or Nelson studs after the company that developed the technology and products for their use and function as weld studs. The function of nelson bolts is the reinforcement of the concrete by welding this product to the steel or structure to act as a single unit which avoids perforation, sealing and weakening of the structure and concrete. Self-welding studs are used for bridges, columns, containments, structures and so on. We also have the ferrules for a better installation of the bolts, since it is necessary to have a special welder so that the work is faster and much more efficient.
