Stainless Steel Weld Bolts Studs are created to DIN 32501 standard and are designed for welding to thin gauge sheet metal. They are also known as Threaded Capacitor Discharge Studs.
Hosting cold-formed pips at the end of the studs, they are applied using a welding gun, with the ignition tips at the base of the stud creating an arc which melts the base of the stud and the fixing surface, creating an instant fusion weld.
Weld studs are fasteners that are used to securely attach objects to a base material through the process of welding. They consist of a threaded or unthreaded rod with a flanged end or a smaller base plate. The stud is welded to the base material by melting the metal and fusing it with the base material.
Weld studs are commonly used in construction, automotive, and manufacturing industries for various applications such as attaching metal plates, brackets, or other components to a structure. They provide a strong and reliable connection, as the welding process creates a bond that is often stronger than the base material itself.
There are different types of weld studs available, including threaded studs, unthreaded studs, shear studs, and CD studs. Threaded studs have a threaded end that allows for the attachment of nuts or other fasteners, while unthreaded studs are used for direct welding. Shear studs are specifically designed to resist shear forces, and CD studs (capacitor discharge studs) are used for quick and efficient welding in thin materials.
Overall, weld studs are versatile fasteners that provide a secure and efficient method of attaching objects to a base material through welding.
