Welding bolts, commonly known as arc stud fasteners, play a crucial role in structural steel fabrication where permanent and high-strength connections are required. Typically manufactured to standards such as DIN ISO 13918, these bolts are designed for use with arc welding equipment, ensuring a fusion bond between the bolt and the base material.
One of the key attributes of welding bolts is their Grade 8.8 or Grade 10.9 tensile strength, providing excellent shear resistance in demanding applications. These bolts are often produced from low-carbon or alloy steels, with surface treatments like zinc plating, black oxide, or plain finish, depending on corrosion resistance requirements.
Common head styles include full base studs and flanged base studs, enabling better weld penetration and load distribution. Diameters typically range from M6 to M24, with lengths customized based on the structural needs. Welding bolts are widely used in automotive chassis manufacturing, construction beams, shipbuilding, and bridge assembly, where safety and durability are non-negotiable.
Compared to mechanical fastening, welding bolts eliminate the need for pre-drilled holes and reduce assembly time, enhancing production efficiency. For OEMs and industrial suppliers, sourcing from a reliable manufacturer ensures consistent performance under thermal and dynamic stress conditions.
As a professional manufacturer and supplier of welding bolts, we provide bulk quantities with full compliance to mechanical and dimensional specifications. All products are tested for tensile load, elongation, and weld integrity, ensuring reliability for critical structural applications.
